Struct Rng 

pub struct Rng<'d, M: Mode> { /* private fields */ }

Driver for the true random number generator.

The AES and public key engines also draw from the generator for their side-channel countermeasures. It keeps running from its first use until the accelerator powers down.

Implementations

impl<'d> Rng<'d, Blocking>

pub fn new_blocking(_peri: Peri<'d, CRYPTO_RNG>) -> Self

Creates a new blocking RNG driver.

impl<'d, M: Mode> Rng<'d, M>

pub fn blocking_fill_bytes(&mut self, dest: &mut [u8])

Fills the buffer with random bytes.

pub fn blocking_next_u32(&mut self) -> u32

Returns a random u32.

pub fn blocking_next_u64(&mut self) -> u64

Returns a random u64.
