Enum rand::rngs::TimerError

pub enum TimerError {
    NoTimer,
    CoarseTimer,
    NotMonotonic,
    TinyVariantions,
    TooManyStuck,
    // some variants omitted
}

An error that can occur when JitterRng::test_timer fails.

Variants

NoTimer

No timer available.

CoarseTimer

Timer too coarse to use as an entropy source.

NotMonotonic

Timer is not monotonically increasing.

TinyVariantions

Variations of deltas of time too small.

TooManyStuck

Too many stuck results (indicating no added entropy).

impl Clone for TimerError

fn clone(&self) -> TimerError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

fn from(err: TimerError) -> Error

Performs the conversion.

impl PartialEq<TimerError> for TimerError

fn eq(&self, other: &TimerError) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
