std::basic_string<CharT,Traits,Allocator>::contains
From cppreference.com
< cpp | string | basic string
| constexpr bool contains( std::basic_string_view<CharT,Traits> sv ) const noexcept; |
(1) | (since C++23) |
| constexpr bool contains( CharT ch ) const noexcept; |
(2) | (since C++23) |
| constexpr bool contains( const CharT* s ) const; |

Checks if the string contains the given substring. The substring 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 are equivalent to return find(x) != npos;, where x is the parameter.
