deduction guides for std::ranges::split_view
From cppreference.com
< cpp | ranges | split view
template< class R, class P > split_view( R&&, P&& ) |
(1) | (since C++20) |
template< ranges::input_range R > split_view( R&&, ranges::range_value_t<R> ) |
(2) | (since C++20) |
These deduction guides are provided for split_view to allow deduction from a range and a delimiter.
1) The delimiter is a range of elements.
2) The delimiter is a single element.
[edit] Example
Run this code
#include <ranges> #include <string_view> #include <type_traits> using std::operator""sv; int main() { std::ranges::split_view w1{"a::b::c"sv, "::"sv}; static_assert(std::is_same_v< decltype(w1), std::ranges::split_view<std::string_view, std::string_view>>); std::ranges::split_view w2{"x,y,z"sv, ','}; static_assert(std::is_same_v< decltype(w2), std::ranges::split_view<std::string_view, std::ranges::single_view<char>>>); }
