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).

Trait Implementations

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 !=.

impl From<TimerError> for Error

fn from(err: TimerError) -> Error

Performs the conversion.

impl Debug for TimerError

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

Formats the value using the given formatter.

impl Error for TimerError

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

The lower-level cause of this error, if any.

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error ocurred.

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.

impl Eq for TimerError

impl Display for TimerError

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

Formats the value using the given formatter.
