Find the first occurrence of a sequence in this string.
Declared in <bslstl_string.h>
template<class STRING_VIEW_LIKE_TYPE>
size_type
find(
STRING_VIEW_LIKE_TYPE const& substring,
size_type position = 0) const noexcept(true);Return the starting position of the first occurrence of the specified substring, if such a substring can be found in this string (on or after the optionally specified position if such a position is specified) using CHAR_TRAITS::eq to compare characters, and return npos otherwise. The behavior is undefined unless the conversion from STRING_VIEW_LIKE_TYPE to `bsl::basic_string_view<CHAR_TYPE, CHAR_TRAITS>` does not throw any exception. Note that this behavior differs from the behavior implemented in the standard container, where the following noexcept specification is used: ` noexcept( std::is_nothrow_convertible_v<const T&, std::basic_string_view<CharT, Traits> >) `
position of the match, or npos if not found
