toml::source_position struct

A source document line-and-column pair.

auto table = toml::parse_file("config.toml"sv);
std::cout << "The node 'description' was defined at "sv
    << table.get("description")->source().begin()
    << "\n";
The value 'description' was defined at line 7, column 15

Constructors, destructors, conversion operators
