How to convert a slice into an array reference?

by

As of Rust 1.34, you can use TryFrom / TryInto:

use std::convert::TryFrom;

fn example(slice: &[u8]) {
    let array = <&[u8; 3]>::try_from(slice);
    println!("{:?}", array);
}

fn example_mut(slice: &mut [u8]) {
    let array = <&mut [u8; 3]>::try_from(slice);
    println!("{:?}", array);
}
