Trait rand_core::block::BlockRngCore

[+] Show declaration

pub trait BlockRngCore {
    type Item;
    type Results: AsRef<[Self::Item]> + AsMut<[Self::Item]> + Default;
    fn generate(&mut self, results: &mut Self::Results);
}

[−] Expand description

A trait for RNGs which do not generate random numbers individually, but in blocks (typically [u32; N]). This technique is commonly used by cryptographic RNGs to improve performance.

See the [module][crate::block] documentation for details.

Associated Types

type Item[−]

Results element type, e.g. u32.

type Results: AsRef<[Self::Item]> + AsMut<[Self::Item]> + Default[−]

Results type. This is the 'block' an RNG implementing BlockRngCore generates, which will usually be an array like [u32; 16].

Required methods

fn generate(&mut self, results: &mut Self::Results)[−]

Generate a new block of results.
