deductiongu...::split_view(3)

💖 NAME 💖

okay so bestie, this page is deductiongu...::split_view(3) from the C++ Standard Libary, and the official NAME is literally:

deductionguidesforstd::ranges::split_view - deductionguidesforstd::ranges::split_view

not me pointing out it’s the same on both sides 😭💅 it’s giving redundant but make it fashion.

✨ Synopsis ✨

these deduction guides are provided for split_view to allow deduction from a range and a delimiter. periodt. two guides, both (since C++20), both iconic 👑

template< class R, class P >

split_view( R&&, P&& )
(1) (since C++20)

    -> split_view<views::all_t<R>, views::all_t<P>>;
template< ranges::input_range R >

split_view( R&&, ranges::range_value_t<R> )
(2) (since C++20)

    -> split_view<views::all_t<R>,
          ranges::single_view<ranges::range_value_t<R>>>;

1. the delimiter is a range of elements.
2. the delimiter is a single element.

🎀 Example 🎀

run this code, it’s right here and it ate:

// 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>>>);
}
