Macro malachite_base::lex_unique_tuples

macro_rules! lex_unique_tuples {
    (
        ($($vis:tt)*),
        $struct: ident,
        $k: expr,
        $out_t: ty,
        $fn: ident,
        [$($i: expr),*]
    ) => { ... };
}

Defines lexicographic unique tuple generators.

Malachite provides lex_unique_pairs, but you can also define lex_unique_triples, lex_unique_quadruples, and so on, in your program using the code below. The documentation for lex_unique_pairs describes these other functions as well.

See usage examples here.
