Find the first occurrence of a string within the string.

Synopsis

template<
    typename T,
    [role red error.class-detail-template.1][role red error.class-detail-template.2] = detail::enable_if_viewable_t<T, CharT, Traits>>
BOOST_STATIC_STRING_CPP14_CONSTEXPR size_type
find(
    const T& t,
    size_type pos = 0) const;

Description

Constructs a temporary string_view_type object sv from t, and finds the first occurrence of sv within the string starting at the index pos.

Complexity

Linear.

Remarks

An empty string is always found.

Template Parameters

Constraints

std::is_convertible<const T&, string_view>::value && !std::is_convertible<const T&, const CharT*>::value.

Return Value

The lowest index idx greater than or equal to pos where each element of [sv.begin(), sv.end()) is equal to that of [begin() + idx, begin() + idx + count) if one exists, and basic_static_string::npos otherwise.
