Type	Name
R	range The underlying range view being formatted.
std::string_view	sep = ", " The string separating each element.
std::string_view	open = "[" The opening string/bracket.

Detailed Description

This struct acts as a wrapper around any std::ranges::range, allowing it to be piped into a standard output stream with configurable separators and bounding characters.

Example Usage

std::vector<int> vec = {1, 2, 3};
std::cout << gl::io::range_formatter{vec} << '\n';
std::cout << gl::io::range_formatter{vec, " | ", "<", ">"} << '\n';

Output:

[1, 2, 3]
<1 | 2 | 3>
