template<container-compatible-range<CharT> R> constexprstd::basic_string& replace_with_range( const_iterator first, | (since C++23) | |
Replaces the characters in the range[
first,
last)
with the characters from the rangerg.
Equivalent to
return replace(first, last,std::basic_string(std::from_range,std::forward<R>(rg), get_allocator()));
Contents |
first, last | - | range of characters that is going to be replaced |
rg | - | acontainer compatible range |
*this
Linear in size ofrg.
If the operation would causesize()
to exceedmax_size()
, throwsstd::length_error.
If an exception is thrown for any reason, this function has no effect (strong exception safety guarantee).
