Struct std::ffi::OsStr
pub struct OsStr { /* fields omitted */ }
Borrowed reference to an OS string (see OsString).
This type represents a borrowed reference to a string in the operating system’s preferred representation.
&OsStr is to OsString as &str is to String: the former in each pair are borrowed references; the latter are owned strings.
See the module’s toplevel documentation about conversions for a discussion on the traits which OsStr implements for conversions from/to native representations.
Implementations
impl OsStr
pub fn new<S: AsRef<OsStr> + ?Sized>(s: &S) -> &OsStr
Coerces into an OsStr slice.
Examples
use std::ffi::OsStr;
let os_str = OsStr::new("foo");pub fn to_str(&self) -> Option<&str>
Yields a &str slice if the OsStr is valid Unicode.
This conversion may entail doing a check for UTF-8 validity.
Examples
use std::ffi::OsStr;
let os_str = OsStr::new("foo");
assert_eq!(os_str.to_str(), Some("foo"));pub fn to_string_lossy(&self) -> Cow<'_, str>
Converts an OsStr to a Cow<str>.
Any non-Unicode sequences are replaced with U+FFFD REPLACEMENT CHARACTER.
Examples
Calling to_string_lossy on an OsStr with invalid unicode:
// Note, due to differences in how Unix and Windows represent strings,
// we are forced to complicate this example, setting up example `OsStr`s
// with different source data and via different platform extensions.
// Understand that in reality you could end up with such example invalid
// sequences simply through collecting user command line arguments, for
// example.
#[cfg(unix)] {
use std::ffi::OsStr;
use std::os::unix::ffi::OsStrExt;
// Here, the values 0x66 and 0x6f correspond to 'f' and 'o'
// respectively. The value 0x80 is a lone continuation byte, invalid
// in a UTF-8 sequence.
let source = [0x66, 0x6f, 0x80, 0x6f];
let os_str = OsStr::from_bytes(&source[..]);
assert_eq!(os_str.to_string_lossy(), "fo�o");
}
#[cfg(windows)] {
use std::ffi::OsString;
use std::os::windows::prelude::*;
// Here the values 0x0066 and 0x006f correspond to 'f' and 'o'
// respectively. The value 0xD800 is a lone surrogate half, invalid
// in a UTF-16 sequence.
let source = [0x0066, 0x006f, 0xD800, 0x006f];
let os_string = OsString::from_wide(&source[..]);
let os_str = os_string.as_os_str();
assert_eq!(os_str.to_string_lossy(), "fo�o");
}pub fn to_os_string(&self) -> OsString
Copies the slice into an owned OsString.
Examples
use std::ffi::{OsStr, OsString};
let os_str = OsStr::new("foo");
let os_string = os_str.to_os_string();
assert_eq!(os_string, OsString::from("foo"));pub fn is_empty(&self) -> bool
Checks whether the OsStr is empty.
Examples
use std::ffi::OsStr;
let os_str = OsStr::new("");
assert!(os_str.is_empty());
let os_str = OsStr::new("foo");
assert!(!os_str.is_empty());pub fn len(&self) -> usize
Returns the length of this OsStr.
Note that this does not return the number of bytes in the string in OS string form.
The length returned is that of the underlying storage used by OsStr. As discussed in the OsString introduction, OsString and OsStr store strings in a form best suited for cheap inter-conversion between native-platform and Rust string forms, which may differ significantly from both of them, including in storage size and encoding.
This number is simply useful for passing to other methods, like OsString::with_capacity to avoid reallocations.
Examples
use std::ffi::OsStr;
let os_str = OsStr::new("");
assert_eq!(os_str.len(), 0);
let os_str = OsStr::new("foo");
assert_eq!(os_str.len(), 3);pub fn into_os_string(self: Box<OsStr>) -> OsString
pub fn make_ascii_lowercase(&mut self)
Converts this string to its ASCII lower case equivalent in-place.
ASCII letters ‘A’ to ‘Z’ are mapped to ‘a’ to ‘z’, but non-ASCII letters are unchanged.
To return a new lowercased value without modifying the existing one, use OsStr::to_ascii_lowercase.
Examples
use std::ffi::OsString;
let mut s = OsString::from("GRÜßE, JÜRGEN ❤");
s.make_ascii_lowercase();
assert_eq!("grÜße, jÜrgen ❤", s);pub fn make_ascii_uppercase(&mut self)
Converts this string to its ASCII upper case equivalent in-place.
ASCII letters ‘a’ to ‘z’ are mapped to ‘A’ to ‘Z’, but non-ASCII letters are unchanged.
To return a new uppercased value without modifying the existing one, use OsStr::to_ascii_uppercase.
Examples
use std::ffi::OsString;
let mut s = OsString::from("Grüße, Jürgen ❤");
s.make_ascii_uppercase();
assert_eq!("GRüßE, JüRGEN ❤", s);pub fn to_ascii_lowercase(&self) -> OsString
Returns a copy of this string where each character is mapped to its ASCII lower case equivalent.
ASCII letters ‘A’ to ‘Z’ are mapped to ‘a’ to ‘z’, but non-ASCII letters are unchanged.
To lowercase the value in-place, use OsStr::make_ascii_lowercase.
Examples
use std::ffi::OsString;
let s = OsString::from("Grüße, Jürgen ❤");
assert_eq!("grüße, jürgen ❤", s.to_ascii_lowercase());pub fn to_ascii_uppercase(&self) -> OsString
Returns a copy of this string where each character is mapped to its ASCII upper case equivalent.
ASCII letters ‘a’ to ‘z’ are mapped to ‘A’ to ‘Z’, but non-ASCII letters are unchanged.
To uppercase the value in-place, use OsStr::make_ascii_uppercase.
Examples
use std::ffi::OsString;
let s = OsString::from("Grüße, Jürgen ❤");
assert_eq!("GRüßE, JüRGEN ❤", s.to_ascii_uppercase());pub fn is_ascii(&self) -> bool
Checks if all characters in this string are within the ASCII range.
Examples
use std::ffi::OsString;
let ascii = OsString::from("hello!\n");
let non_ascii = OsString::from("Grüße, Jürgen ❤");
assert!(ascii.is_ascii());
assert!(!non_ascii.is_ascii());pub fn eq_ignore_ascii_case<S: AsRef<OsStr>>(&self, other: S) -> bool
Checks that two strings are an ASCII case-insensitive match.
Same as to_ascii_lowercase(a) == to_ascii_lowercase(b), but without allocating and copying temporaries.
Examples
use std::ffi::OsString;
assert!(OsString::from("Ferris").eq_ignore_ascii_case("FERRIS"));
assert!(OsString::from("Ferrös").eq_ignore_ascii_case("FERRöS"));
assert!(!OsString::from("Ferrös").eq_ignore_ascii_case("FERRÖS"));Trait Implementations
