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 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 Debug for TimerError

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

Formats the value using the given formatter.

impl Display for TimerError

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

Formats the value using the given formatter.

impl Eq for TimerError

impl Error for TimerError

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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 occurred.

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<TimerError> for Error

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 !=.
