Primitive Type i64
The 64-bit signed integer type.
Implementations
impl i64
pub fn widening_mul(self, rhs: i64) -> (i64, i64)
Calculates the complete product self * rhs
without the possibility to overflow.
This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.
Examples
Basic usage:
Please note that this example is shared between integer types. Which explains why u32
is used here.
#![feature(bigint_helper_methods)] assert_eq!(5u32.widening_mul(2), (10, 0)); assert_eq!(1_000_000_000u32.widening_mul(10), (1410065408, 2));
pub fn carrying_mul(self, rhs: i64, carry: i64) -> (i64, i64)
Calculates the “full multiplication” self * rhs + carry
without the possibility to overflow.
This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.
Performs “long multiplication” which takes in an extra amount to add, and may return an additional amount of overflow. This allows for chaining together multiple multiplications to create “big integers” which represent larger values.

pub const fn wrapping_div(self, rhs: i64) -> i64
Wrapping (modular) division. Computes self / rhs
, wrapping around at the boundary of the type.
The only case where such wrapping can occur is when one divides MIN / -1
on a signed type (where MIN
is the negative minimal value for the type); this is equivalent to -MIN
, a positive value that is too large to represent in the type. In such a case, this function returns MIN
itself.
Panics
This function will panic if rhs
is 0.
Examples

pub const fn wrapping_div_euclid(self, rhs: i64) -> i64
Wrapping Euclidean division. Computes self.div_euclid(rhs)
, wrapping around at the boundary of the type.
Wrapping will only occur in MIN / -1
on a signed type (where MIN
is the negative minimal value for the type). This is equivalent to -MIN
, a positive value that is too large to represent in the type. In this case, this method returns MIN
itself.
Panics

pub const fn wrapping_rem(self, rhs: i64) -> i64
Wrapping (modular) remainder. Computes self % rhs
, wrapping around at the boundary of the type.
Such wrap-around never actually occurs mathematically; implementation artifacts make x % y
invalid for MIN / -1
on a signed type (where MIN
is the negative minimal value). In such a case, this function returns 0
.
Panics
This function will panic if rhs
is 0.
Examples
Basic usage:
assert_eq!(100i64.wrapping_rem(10), 0); assert_eq!((-128i8).wrapping_rem(-1), 0);
pub const fn wrapping_rem_euclid(self, rhs: i64) -> i64
Wrapping Euclidean remainder. Computes self.rem_euclid(rhs)
, wrapping around at the boundary of the type.
Wrapping will only occur in MIN % -1
on a signed type (where MIN
is the negative minimal value for the type). In this case, this method returns 0.
Panics
This function will panic if rhs
is 0.
Examples
Basic usage:

, wrapping around at the boundary of the type.
The only case where such wrapping can occur is when one negates MIN
on a signed type (where MIN
is the negative minimal value for the type); this is a positive value that is too large to represent in the type. In such a case, this function returns MIN
itself.
Examples
Basic usage:
assert_eq!(100i64.wrapping_neg(), -100); assert_eq!(i64::MIN.wrapping_neg(), i64::MIN);
pub const fn wrapping_shl(self, rhs: u32) -> i64
Panic-free bitwise shift-left; yields self << mask(rhs)
, where mask
removes any high-order bits of rhs
that would cause the shift to exceed the bitwidth of the type.
Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_left
function, which may be what you want instead.
Examples
Basic usage:
assert_eq!((-1i64).wrapping_shl(7), -128); assert_eq!((-1i64).wrapping_shl(128), -1);
pub const fn wrapping_shr(self, rhs: u32) -> i64
Panic-free bitwise shift-right; yields self >> mask(rhs)
, where mask
removes any high-order bits of rhs
that would cause the shift to exceed the bitwidth of the type.
Note that this is not the same as a rotate-right; the RHS of a wrapping shift-right is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_right
function, which may be what you want instead.

The only case where such wrapping can occur is when one takes the absolute value of the negative minimal value for the type; this is a positive value that is too large to represent in the type. In such a case, this function returns MIN
itself.
Examples
Basic usage:
assert_eq!(100i64.wrapping_abs(), 100); assert_eq!((-100i64).wrapping_abs(), 100); assert_eq!(i64::MIN.wrapping_abs(), i64::MIN); assert_eq!((-128i8).wrapping_abs() as u8, 128);

pub const fn overflowing_neg(self) -> (i64, bool)
Negates self, overflowing if this is equal to the minimum value.
Returns a tuple of the negated version of self along with a boolean indicating whether an overflow happened. If self
is the minimum value (e.g., i32::MIN
for values of type i32
), then the minimum value will be returned again and true
will be returned for an overflow happening.
Examples
Basic usage:
assert_eq!(2i64.overflowing_neg(), (-2, false)); assert_eq!(i64::MIN.overflowing_neg(), (i64::MIN, true));
pub const fn overflowing_shl(self, rhs: u32) -> (i64, bool)
Shifts self left by rhs
bits.
Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.
Examples
Basic usage:
assert_eq!(0x1i64.overflowing_shl(4), (0x10, false)); assert_eq!(0x1i32.overflowing_shl(36), (0x10, true));
pub const fn overflowing_shr(self, rhs: u32) -> (i64, bool)
Shifts self right by rhs
bits.
Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.
Examples
Basic usage:
assert_eq!(0x10i64.overflowing_shr(4), (0x1, false)); assert_eq!(0x10i32.overflowing_shr(36), (0x1, true));
pub const fn overflowing_abs(self) -> (i64, bool)
Computes the absolute value of self
.
Returns a tuple of the absolute version of self along with a boolean indicating whether an overflow happened. If self is the minimum value (e.g., i64::MIN for values of type i64), then the minimum value will be returned again and true will be returned for an overflow happening.
Examples
Basic usage:
assert_eq!(10i64.overflowing_abs(), (10, false)); assert_eq!((-10i64).overflowing_abs(), (10, false)); assert_eq!((i64::MIN).overflowing_abs(), (i64::MIN, true));
pub const fn overflowing_pow(self, exp: u32) -> (i64, bool)
Raises self to the power of exp
, using exponentiation by squaring.
Returns a tuple of the exponentiation along with a bool indicating whether an overflow happened.
Examples
Basic usage:
assert_eq!(3i64.overflowing_pow(4), (81, false)); assert_eq!(3i8.overflowing_pow(5), (-13, true));
pub const fn pow(self, exp: u32) -> i64
Raises self to the power of exp
, using exponentiation by squaring.
Examples
Basic usage:
let x: i64 = 2; // or any other integer type assert_eq!(x.pow(5), 32);
pub const fn div_euclid(self, rhs: i64) -> i64
Calculates the quotient of Euclidean division of self
by rhs
.
This computes the integer q
such that self = q * rhs + r
, with r = self.rem_euclid(rhs)
and 0 <= r < abs(rhs)
.
In other words, the result is self / rhs
rounded to the integer q
such that self >= q * rhs
. If self > 0
, this is equal to round towards zero (the default in Rust); if self < 0
, this is equal to round towards +/- infinity.
Panics
This function will panic if rhs
is 0 or the division results in overflow.
Examples
Basic usage:
let a: i64 = 7; // or any other integer type let b = 4; assert_eq!(a.div_euclid(b), 1); // 7 >= 4 * 1 assert_eq!(a.div_euclid(-b), -1); // 7 >= -4 * -1 assert_eq!((-a).div_euclid(b), -2); // -7 >= 4 * -2 assert_eq!((-a).div_euclid(-b), 2); // -7 >= -4 * 2
pub const fn rem_euclid(self, rhs: i64) -> i64
Calculates the least nonnegative remainder of self (mod rhs)
.
This is done as if by the Euclidean division algorithm – given r = self.rem_euclid(rhs)
, self = rhs * self.div_euclid(rhs) + r
, and 0 <= r < abs(rhs)
.
Panics
This function will panic if rhs
is 0 or the division results in overflow.
Examples
Basic usage:
let a: i64 = 7; // or any other integer type let b = 4; assert_eq!(a.rem_euclid(b), 3); assert_eq!((-a).rem_euclid(b), 1); assert_eq!(a.rem_euclid(-b), 3); assert_eq!((-a).rem_euclid(-b), 1);
pub const fn unstable_div_floor(self, rhs: i64) -> i64

and rhs
, rounding the result towards negative infinity.

#![feature(int_roundings)] let a: i64 = 8; let b = 3; assert_eq!(a.unstable_div_floor(b), 2); assert_eq!(a.unstable_div_floor(-b), -3); assert_eq!((-a).unstable_div_floor(b), -3); assert_eq!((-a).unstable_div_floor(-b), 2);
pub const fn unstable_div_ceil(self, rhs: i64) -> i64

is positive, calculates the smallest value greater than or equal to self
that is a multiple of rhs
. If rhs
is negative, calculates the largest value less than or equal to self

is positive, calculates the smallest value greater than or equal to self
that is a multiple of rhs
. If rhs
is negative, calculates the largest value less than or equal to self
that is a multiple of rhs
. Returns None
if rhs
is zero or the operation would result in overflow.
Examples
Basic usage:
#![feature(int_roundings)] assert_eq!(16_i64.checked_next_multiple_of(8), Some(16)); assert_eq!(23_i64.checked_next_multiple_of(8), Some(24)); assert_eq!(16_i64.checked_next_multiple_of(-8), Some(16)); assert_eq!(23_i64.checked_next_multiple_of(-8), Some(16)); assert_eq!((-16_i64).checked_next_multiple_of(8), Some(-16)); assert_eq!((-23_i64).checked_next_multiple_of(8), Some(-16)); assert_eq!((-16_i64).checked_next_multiple_of(-8), Some(-16)); assert_eq!((-23_i64).checked_next_multiple_of(-8), Some(-24)); assert_eq!(1_i64.checked_next_multiple_of(0), None); assert_eq!(i64::MAX.checked_next_multiple_of(2), None);
pub const fn log(self, base: i64) -> i64
Returns the logarithm of the number with respect to an arbitrary base.
This method might not be optimized owing to implementation details; log2
can produce results more efficiently for base 2, and log10
can produce results more efficiently for base 10.
Panics
When the number is zero, or if the base is not at least 2; it panics in debug mode and the return value is wrapped to 0 in release mode (the only situation in which the method can return 0).
Examples
#![feature(int_log)] assert_eq!(5i64.log(5), 1);
pub const fn log2(self) -> i64
Returns the base 2 logarithm of the number.
Panics
When the number is zero it panics in debug mode and the return value is wrapped to 0 in release mode (the only situation in which the method can return 0).
Examples
#![feature(int_log)] assert_eq!(2i64.log2(), 1);
pub const fn log10(self) -> i64
Returns the base 10 logarithm of the number.
Panics
When the number is zero it panics in debug mode and the return value is wrapped to 0 in release mode (the only situation in which the method can return 0).
Example
#![feature(int_log)] assert_eq!(10i64.log10(), 1);
pub const fn checked_log(self, base: i64) -> Option<i64>
Returns the logarithm of the number with respect to an arbitrary base.
Returns None
if the number is negative or zero, or if the base is not at least 2.
This method might not be optimized owing to implementation details; checked_log2
can produce results more efficiently for base 2, and checked_log10
can produce results more efficiently for base 10.
Examples
#![feature(int_log)] assert_eq!(5i64.checked_log(5), Some(1));
pub const fn checked_log2(self) -> Option<i64>
Returns the base 2 logarithm of the number.
Returns None
if the number is negative or zero.
Examples
#![feature(int_log)] assert_eq!(2i64.checked_log2(), Some(1));
pub const fn checked_log10(self) -> Option<i64>
Returns the base 10 logarithm of the number.

Example
#![feature(int_log)] assert_eq!(10i64.checked_log10(), Some(1));
pub const fn abs(self) -> i64
Computes the absolute value of self
.
Overflow behavior
The absolute value of i64::MIN
cannot be represented as an i64
, and attempting to calculate it will cause an overflow. This means that code in debug mode will trigger a panic on this case and optimized code will return i64::MIN
without a panic.
Examples
Basic usage:
assert_eq!(10i64.abs(), 10); assert_eq!((-10i64).abs(), 10);
pub const fn signum(self) -> i64
Returns a number representing sign of self
.
-
0
if the number is zero -
1
if the number is positive -
-1
if the number is negative
Examples
Basic usage:
assert_eq!(10i64.signum(), 1); assert_eq!(0i64.signum(), 0); assert_eq!((-10i64).signum(), -1);
pub const fn is_positive(self) -> bool
Returns true
if self
is positive and false
if the number is zero or negative.
Examples
Basic usage:
assert!(10i64.is_positive()); assert!(!(-10i64).is_positive());
pub const fn is_negative(self) -> bool
Returns true
if self
is negative and false
if the number is zero or positive.
Examples
Basic usage:
assert!((-10i64).is_negative()); assert!(!10i64.is_negative());

Return the memory representation of this integer as a byte array in big-endian (network) byte order.
Examples
let bytes = 0x1234567890123456i64.to_be_bytes(); assert_eq!(bytes, [0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56]);
pub const fn to_le_bytes(self) -> [u8; 8]
Return the memory representation of this integer as a byte array in little-endian byte order.
Examples
let bytes = 0x1234567890123456i64.to_le_bytes(); assert_eq!(bytes, [0x56, 0x34, 0x12, 0x90, 0x78, 0x56, 0x34, 0x12]);
pub const fn to_ne_bytes(self) -> [u8; 8]
Return the memory representation of this integer as a byte array in native byte order.
As the target platform’s native endianness is used, portable code should use to_be_bytes
or to_le_bytes
, as appropriate, instead.
Examples
let bytes = 0x1234567890123456i64.to_ne_bytes(); assert_eq!( bytes, if cfg!(target_endian = "big") { [0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56] } else { [0x56, 0x34, 0x12, 0x90, 0x78, 0x56, 0x34, 0x12] } );
pub const fn from_be_bytes(bytes: [u8; 8]) -> i64
Create an integer value from its representation as a byte array in big endian.
Examples
let value = i64::from_be_bytes([0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56]); assert_eq!(value, 0x1234567890123456);
When starting from a slice rather than an array, fallible conversion APIs can be used:
use std::convert::TryInto; fn read_be_i64(input: &mut &[u8]) -> i64 { let (int_bytes, rest) = input.split_at(std::mem::size_of::<i64>()); *input = rest; i64::from_be_bytes(int_bytes.try_into().unwrap()) }

When starting from a slice rather than an array, fallible conversion APIs can be used:
use std::convert::TryInto; fn read_le_i64(input: &mut &[u8]) -> i64 { let (int_bytes, rest) = input.split_at(std::mem::size_of::<i64>()); *input = rest; i64::from_le_bytes(int_bytes.try_into().unwrap()) }
pub const fn from_ne_bytes(bytes: [u8; 8]) -> i64
Create an integer value from its memory representation as a byte array in native endianness.
As the target platform’s native endianness is used, portable code likely wants to use from_be_bytes
or from_le_bytes
, as appropriate instead.
Examples
let value = i64::from_ne_bytes(if cfg!(target_endian = "big") { [0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56] } else { [0x56, 0x34, 0x12, 0x90, 0x78, 0x56, 0x34, 0x12] }); assert_eq!(value, 0x1234567890123456);
When starting from a slice rather than an array, fallible conversion APIs can be used:
use std::convert::TryInto; fn read_ne_i64(input: &mut &[u8]) -> i64 { let (int_bytes, rest) = input.split_at(std::mem::size_of::<i64>()); *input = rest; i64::from_ne_bytes(int_bytes.try_into().unwrap()) }
pub const fn min_value() -> i64
replaced by the MIN
associated constant on this type
New code should prefer to use i64::MIN
instead.
Returns the smallest value that can be represented by this integer type.
pub const fn max_value() -> i64
replaced by the MAX
associated constant on this type
New code should prefer to use i64::MAX
instead.
