Macro spectra::gtup

macro_rules! gtup {
    ( : $ ( $ a : tt ) * ) => { ... };
    ( $ ( $ a : tt ) * ) => { ... };
}

Generalized free tuple macro.

If your compiler supports the type_macrosfeature, you can use this macro to create tuples without the syntactic nesting boilerplate.

Furthermore, you can create values with this macro as well.

Examples

// type
type Foo = GTup<i32, Chain<bool, f32>>;
type Zoo = gtup!(:i32, bool, f32); // exactly the same type

// value
let triple = gtup!(42, false, 3.1415);
