Function par_ref_map 

pub fn par_ref_map<'a, Brand: ParRefFunctor, A: Send + Sync + 'a, B: Send + 'a>(
    f: impl Fn(&A) -> B + Send + Sync + 'a,
    fa: &Brand::Of<'a, A>,
) -> Brand::Of<'a, B>

Maps a function over a structure by reference in parallel.

Free function version that dispatches to the type class’ associated function.

Type Signature

forall Brand A B. ParRefFunctor Brand => (&A -> B, &Brand A) -> Brand B

Type Parameters

• 'a: The lifetime of the elements.
• Brand: The brand of the structure.
• A: The input element type.
• B: The output element type.

Parameters

• f: The function to apply to each element reference. Must be Send + Sync.
• fa: The structure to map over.

Returns

A new structure containing the mapped elements.

Examples

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

let v = vec![1, 2, 3];
let result = par_ref_map::<VecBrand, _, _>(|x: &i32| x * 2, &v);
assert_eq!(result, vec![2, 4, 6]);
