Trait frunk::hlist::IntoTuple2[−][src]

pub trait IntoTuple2 {
    type HeadType;
    type TailOutput;
    fn into_tuple2(self) -> (Self::HeadType, Self::TailOutput);
}
Expand description

Trait for transforming an HList into a nested tuple.

This trait is part of the implementation of the inherent method HCons::into_tuple2. Please see that method for more information.

This operation is not useful in generic contexts, so it is unlikely that you should ever need to import this trait. Do not worry; if you have an HList of known type, then list.into_tuple2() should “just work,” even without the trait.

Associated Types

The 0 element in the output tuple

The 1 element in the output tuple

Required methods

Turns an HList into nested Tuple2s, which are less troublesome to pattern match and have a nicer type signature.

Please see the inherent method for more information.
