      1) Replaces the contents of*this with a pathname whose both native and generic format representations equal those ofp.
      2) Replaces the contents of*this with a pathname whose both native and generic format representations equal those ofp, 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-formatsource, which is left in valid, but unspecified state. Equivalent toassign(std::move(source)).
      4) Replaces the contents of*this with a new path value constructed from detected-formatsource as if by overload(4) of thepath constructor. Equivalent toassign(source).

      (4) participates in overload resolution only ifSource andpath are not the same type, and either:

      [edit]Parameters

      p - a path to assign
      source - astd::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

      [edit]Return value

      *this

      [edit]Example

      Run this code
      #include <filesystem>namespace fs= std::filesystem; int main(){    fs::path p="C:/users/abcdef/AppData/Local";    p= p/"Temp";// move assignmentconstwchar_t* wstr= L"D:/猫.txt";    p= wstr;// assignment from a source}
