std::filesystem::path::assign - cppreference.com (original) (raw)

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.

Assigns the pathname identified by the detected-format string source, which is left in valid, but unspecified state.
Assigns the pathname identified by the detected-format character range source.
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).

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)
