Module traversable 

Data structures that can be traversed, accumulating results in an applicative context.

Examples

use fp_library::{
	brands::*,
	functions::explicit::*,
};

let x = Some(5);
let y = traverse::<RcFnBrand, OptionBrand, _, _, OptionBrand, _, _>(|a| Some(a * 2), x);
assert_eq!(y, Some(Some(10)));

Traits

Traversable

A type class for traversable functors.

Functions

sequence

Evaluate each computation in a Traversable structure and accumulate the results into an Applicative context.

traverse

Map each element of the Traversable structure to a computation, evaluate those computations and combine the results into an Applicative context.
