Expand description

Enables the types which implements FnOnce to be called with arguments tuple.

use tuple_fn::TupleFnOnce;

let start = "hello".to_string();

let closure = move |s1, s2| {
    let mut start = start;
    start.push_str(" ");
    start.push_str(s1);
    start.push_str(" ");
    start.push_str(s2);
    start
};

let result = closure.call_once_with_args_tuple(("world", "!"));

assert_eq!(result, "hello world !");
