Struct async_weighted_semaphore::PoisonError

pub struct PoisonError;

An error returned by Semaphore::acquire and Semaphore::acquire_arc to indicate the Semaphore has been poisoned. See Semaphore::acquire_arc for an example usage.

Trait Implementations

impl Clone for PoisonError

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

Performs copy-assignment from source.

impl Copy for PoisonError

impl Debug for PoisonError

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

Formats the value using the given formatter.

impl Default for PoisonError

fn default() -> PoisonError

Returns the "default value" for a type.

impl Display for PoisonError

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

impl Eq for PoisonError

impl Error for PoisonError

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 description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<PoisonError> for TryAcquireError

fn from(_: PoisonError) -> Self

Performs the conversion.

impl Hash for PoisonError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for PoisonError

fn cmp(&self, other: &PoisonError) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl PartialEq<PoisonError> for PoisonError

fn eq(&self, other: &PoisonError) -> 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 PartialOrd<PoisonError> for PoisonError

fn partial_cmp(&self, other: &PoisonError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
