Module rand 

Cryptographic pseudo-random number generation.

An application should create a single SystemRandom and then use it for all randomness generation. See SystemRandom’s documentation for more details.

Example

use aws_lc_rs::{rand, rand::SecureRandom};

//  Using `rand::fill`
let mut rand_bytes = [0u8; 32];
rand::fill(&mut rand_bytes).unwrap();

// Using `SystemRandom`
let rng = rand::SystemRandom::new();
rng.fill(&mut rand_bytes).unwrap();

// Using `rand::generate`
let random_array = rand::generate(&rng).unwrap();
let more_rand_bytes: [u8; 64] = random_array.expose();

Structs

Random

A random value constructed from a SecureRandom that hasn’t been exposed through any safe Rust interface.

SystemRandom

A secure random number generator where the random values come from the underlying AWS-LC libcrypto.

Traits

RandomlyConstructable

A type that can be returned by aws_lc_rs::rand::generate().

SecureRandom

A secure random number generator.

Functions

fill

Fills dest with random bytes.

generate

Generate the new random value using rng.
