luminance::chain! [−] [src]

macro_rules! chain {
    ($t:ty) => { ... };
    ($a:ty, $($r:tt)*) => { ... };
}

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

Examples

type Foo = Chain<i32,Chain<bool,f32>>;
type Zoo = chain![i32, bool, f32]; // exactly the same type
