begin,end(std::basic_string_view)
constexpr const_iterator begin(basic_string_view sv) noexcept; | (1) | (since C++20) |
constexpr const_iterator end(basic_string_view sv) noexcept; | (2) | (since C++20) |
1) Returns an iterator to the first character of the view. Equivalent to
sv.begin()
.
2) Returns an iterator to the character following the last character of the view. Equivalent to
sv.end()
.These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::basic_string_view<CharT, Traits>
is an associated class of the arguments.
Parameters
sv | - | a string_view |
Return value
1)
sv.begin()
2)
sv.end()
Notes
These functions are provided to make string_view
rvalues work with std::ranges::begin
and std::ranges::end
, which reject rvalue arguments by default in order to prevent dangling iterator.
