std::ranges::lazy_split_view
constexpr V base ( ) const & requires std:: copy_constructible < V > ;

constexpr V base ( ) && ;

Returns a copy of the underlying view.

1) Copy constructs the result from the underlying view.
2) Move constructs the result from the underlying view.

Parameters

(none)

Return value

A copy of the underlying view.

Example

Run this code 
#include <iostream>
#include <ranges>
#include <string_view>
 
void print(std::string_view rem, auto const& r, std::string_view post = "\n") {
    for (std::cout << rem; auto const& e : r)
        std::cout << e;
    std::cout << post;
}
 
int main()
{
    constexpr std::string_view keywords{ "this,..throw,..true,..try,.." };
    constexpr std::string_view pattern{",.."};
    constexpr std::ranges::lazy_split_view lazy_split_view{keywords, pattern};
    print("base() = [", lazy_split_view.base(), "]\n"
          "substrings: ");
    for (auto const& split: lazy_split_view)
        print("[", split, "] ");
}

Output: 

base() = [this,..throw,..true,..try,..]
substrings: [this] [throw] [true] [try] []
