std::filesystem::path::operator=
| path& operator=( const path& p ); | (1) | (since C++17) | 
| path& operator=( path&& p ) noexcept; | (2) | (since C++17) | 
| path& operator=( string_type&& source ); | (3) | (since C++17) | 
| template< class Source > path& operator=( const Source& source ); | (4) | (since C++17) | 
1) Replaces the contents of 
 *this with a pathname whose both native and generic format representations equal those of p.
2) Replaces the contents of 
 *this with a pathname whose both native and generic format representations equal those of p, possibly using move semantics: p is left in a valid, but unspecified state.
3) Replaces the contents of 
 *this with a new path value constructed from detected-format source, which is left in valid, but unspecified state. Equivalent to assign(std::move(source)).
4) Replaces the contents of 
 *this with a new path value constructed from detected-format source as if by overload (4) of the path constructor. Equivalent to assign(source).Parameters
| p | - | a path to assign | 
| source | - | a std::basic_string,std::basic_string_view, pointer to a null-terminated character/wide character string, or an input iterator that points to a null-terminated character/wide character sequence. The character type must be one ofchar,char8_t,  (since C++20)char16_t,char32_t,wchar_t | 
Return value
*this.
Example
#include <filesystem>
namespace fs = std::filesystem;
int main()
{
    fs::path p = "C:/users/abcdef/AppData/Local";
    p = p / "Temp"; // move assignment
    const wchar_t* wstr = L"D:/猫.txt";
    p = wstr; // assignment from a source
