transvec

transvec is a crate for transmuting Vecs without copying.

Installation

Add this to your Cargo.toml:

[dependencies]
transvec = "0.3"

Usage

use transvec::transmute_vec;
let input: Vec<u8> = vec![1, 2, 3, 4];
let output: Vec<u16, _> = transmute_vec(input).unwrap();

#![no_std]

This supports no_std, just disable the default features, and optionally enable allocator_api, which in addition requires atomic pointers. It does require alloc though.

Nightly

This is nightly because it's blocked on the allocator_api, which is how this crate can get around the aligment issue.

You can however turn off default features, and optionally enable std to make it work on stable, with the only options being transmute_vec_basic and transmute_vec_basic_may_copy.
