std::basic_string<CharT,Traits,Allocator>::ends_with
From cppreference.com
< cpp | string | basic string
constexprbool ends_with(std::basic_string_view<CharT, Traits> sv )constnoexcept; | (1) | (since C++20) |
constexprbool ends_with( CharT ch )constnoexcept; | (2) | (since C++20) |
constexprbool ends_with(const CharT* s )const; | (3) | (since C++20) |
Checks if the string ends with the given suffix. The suffix may be one of the following:
1) A string view sv (which may be a result of implicit conversion from another
std::basic_string
).2) A single character ch.
3) A null-terminated character string s.
All three overloads effectively return std::basic_string_view<CharT, Traits>(data(), size()).ends_with(x), where x
is the parameter.
