Module alternative 

Alternative functors, combining Applicative and Plus.

Alternative provides the ability to choose between computations (via Alt) with an identity element (via Plus), combined with applicative lifting (via Applicative).

Examples

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

// guard filters based on a condition
let result: Vec<()> = guard::<VecBrand>(true);
assert_eq!(result, vec![()]);

let result: Vec<()> = guard::<VecBrand>(false);
assert_eq!(result, vec![]);

Traits

Alternative

A type class combining Applicative and Plus.

Functions

guard

Fails using Plus if a condition does not hold, or succeeds using Applicative if it does.
