std::filesystem::path::assign(3)

NAME
std::filesystem::path::assign - std::filesystem::path::assign

Synopsis
   path& assign( string_type&& source ); (1) (since C++17)
   template< class Source > (2) (since C++17)
   path& assign( const Source& source );
   template< class InputIt > (3) (since C++17)
   path& assign( InputIt first, InputIt last );
   Replaces the contents to the path object by a new pathname constructed from the
   given character sequence.
   1) Assigns the pathname identified by the detected-format string source, which is
   left in valid, but unspecified state.
   2) Assigns the pathname identified by the detected-format character range source.
   3) Assigns the pathname identified by detected-format character range [first, last).
   (2) participates in overload resolution only if Source and path are not the same
   type, and either:
     * Source is a specialization of std::basic_string or std::basic_string_view, or
     * std::iterator_traits<std::decay_t<Source>>::value_type is valid and denotes a
       possibly const-qualified encoding character type (char,
       char8_t,
       (since C++20)char16_t, char32_t, or wchar_t).

Parameters
                 a character range to use, represented as std::string,
   source - std::string_view, pointer to a null-terminated multibyte string, or as
                 an input iterator with char value type that points to a
                 null-terminated multibyte string
   first, last - a character range to use

Type requirements
   -
   InputIt must meet the requirements of LegacyInputIterator.
   -
   The value type of InputIt must be one of the encoded character types (char, wchar_t,
   char16_t and char32_t)

Return value
   *this
