Struct Rng

pub struct Rng { /* private fields */ }

Random number generator driver

Implementations

impl Rng

pub fn new(_rng: impl Peripheral<P = RNG>) -> Self

Create a new random number generator instance

pub fn random(&mut self) -> u32

Reads currently available u32 integer from RNG

pub fn read(&mut self, buffer: &mut [u8])

Reads enough bytes from hardware random number generator to fill buffer.

If any error is encountered then this function immediately returns. The contents of buf are unspecified in this case.

If this function returns an error, it is unspecified how many bytes it has read, but it will never read more than would be necessary to completely fill the buffer.
