slice_mip – Mutate a slice in place with a map function

Documentation

This crate provides a convenience utility for replacing the items in a slice with the result of a map function applied to each item.

Example

use slice_mip::MapInPlace;

let mut buf = [1, 2, 3, 4];
buf.map_in_place(|x| x * 2);

assert_eq!(buf, [2, 4, 6, 8]);

Usage

This crate can be used through cargo by adding it as a dependency in Cargo.toml:

[dependencies]
slice_mip = "1.0.0"

and importing it in the crate root:

extern crate slice_mip;

The provided slice method can then be used by importing the trait within individual modules:

use slice_mip::MapInPlace;

lib.rs:

Mutate a slice in place with a map function.

Note that the map result type must be the same as the input type.

Example

use slice_mip::MapInPlace;

let mut buf = [1, 2, 3, 4];
buf.map_in_place(|x| x * 2);

assert_eq!(buf, [2, 4, 6, 8]);
