Struct Trng 

pub struct Trng { /* private fields */ }

The true random number generator.

Implementations

impl Trng

pub fn new(reg: TRNG, sample_mode: SampleMode, retry_count: RetryCount) -> Self

Create a TRNG given a sampling mode and retry count.

To select the default sampling mode and retry counts, use Default::default().

pub fn next_u32(&mut self) -> Result<u32, Error>

Return the next randomly-generated u32. May need to retrieve another block of random numbers.

Returns “would block” if we’re not ready to read entropy; try again. See the module-level example for how to block.

pub fn release_disabled(self) -> TRNG

Release the TRNG in a disabled state.

This preserves any previously set retry count, sample mode, and peripheral settings. However, the register block is returned in a disabled state.

Trait Implementations

impl Debug for Trng

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
