Trait ByteArray

Source

pub trait ByteArray<const LENGTH: usize>: Bytes {
    // Required method
    fn as_array(&self) -> &[u8; LENGTH];
}

Expand description

Fixed-length byte array.

Implemented only by fixed-size storage such as [u8; LENGTH], StackByteArray, and the protected heap arrays, so the length is checked at compile time. Convert runtime-length input with StackByteArray::try_from or <[u8; LENGTH]>::try_from, which reject any length other than LENGTH.

Slices and vectors are not fixed-length byte arrays:

use dryoc::dryocsecretbox::{DryocSecretBox, Nonce};
use dryoc::types::*;

let key = vec![0u8; 32];
let nonce = Nonce::generate();
DryocSecretBox::encrypt_to_vecbox(b"hello", &nonce, &key);

use dryoc::dryocsecretbox::{DryocSecretBox, Nonce};
use dryoc::types::*;

let key: &[u8] = &[0u8; 32];
let nonce = Nonce::generate();
DryocSecretBox::encrypt_to_vecbox(b"hello", &nonce, &key);

Required Methods§

Source

fn as_array(&self) -> &[u8; LENGTH]

Returns a reference to the underlying fixed-length byte array.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
