path& assign( string_type&& source );
(1) (since C++17)
template< class Source >
path& assign( const Source& source );
(2) (since C++17)
template< class InputIt >
path& assign( InputIt first, InputIt last );
(3) (since C++17)

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:

Parameters

source - a character range to use, represented as std::string, 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
