Module frunk_core::hlist [−] [src]

Module that holds HList data structures and implementations

Typically, you would want to use the hlist! macro to make it easier for you to use HList.

let h = hlist![1, "hi"];
assert_eq!(h.length(), 2);
let (a, b) = h.into_tuple2();
assert_eq!(a, 1);
assert_eq!(b, "hi");

Structs

HCons	Represents the most basic non-empty HList. Its value is held in `head` while its tail is another HList.
HNil	Represents the right-most end of a heterogeneous list
Here	Largely lifted from https://github.com/Sgeo/hlist/blob/master/src/lib.rs#L30 Used as an index into an `HList`.
There	Used as an index into an `HList`.

HFoldRightable	Foldr for HLists
HList	Typeclass for HList-y behaviour
HMappable	Trail that allow for mapping over a data structure using mapping functions stored in another data structure
HZipFoldLeftable	Left fold for a given data structure
IntoReverse	Trait that allows for reversing a given data structure.
IntoTuple2	Trait for things that can be turned into a Tuple 2 (pair)
Selector	Trait for retrieving an HList element by type

Takes an element and an Hlist and returns another one with the element prepended to the original list. The original list is consumed
