Crate hlist [−] [src]

This crate provides types Nil and Cons<H, T>, which together allow for creating lists consisting of multiple types. The types in the list are present in the type of the list, so that Cons<i32, Cons<i64, Nil>> contains an i32 and an i64. If type T is present exactly once in an HList, it is usually possible to allow the compiler to find the T in the HList by using the Find trait.

Structs

Cons	An `HList` with `H` at position 0, and `T` as the rest of the list.
Nil	The empty `HList`.
There	Used as an index into an `HList`.

Enums

Here	Used as an index into an `HList`.

Traits

Find	`Find<T, I>` is implemented for an `HList` if index `I` of the `HList` is a `T`
HList	A marker trait that `Nil` and `Cons<H, T>` satisfies. Not currently used to enforce proper hlists, although this may change. Provides the `push()` method
