std::basic_string<CharT,Traits,Allocator>::assign_range

< cpp‎ | string‎ | basic string
template< container-compatible-range<CharT> R >
constexpr std::basic_string& assign_range( R&& rg );
 (since C++23)

Replaces the contents of the string with the values in the range rg.

Equivalent to

return assign(
    std::basic_string(
        std::from_range,
        std​::​forward<R>(rg),
        get_allocator())
);

Parameters

rg - a container compatible range

Return value

*this

Complexity

Linear in size of rg.

Exceptions

If the operation would result in size() > max_size(), throws std::length_error.

If an exception is thrown for any reason, this function has no effect (strong exception safety guarantee).
