Enum TryAcquireError

pub enum TryAcquireError {
    Closed,
    NoPermits,
}

An error which can occur when a Semaphore has been closed or has no available permits.

Variants

Closed

The semaphore has been closed and can not issue new permits.

NoPermits

The semaphore has no available permits.

Trait Implementations

impl Clone for TryAcquireError

fn clone(&self) -> TryAcquireError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TryAcquireError

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

Formats the value using the given formatter.

impl Display for TryAcquireError

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

Formats the value using the given formatter.

impl PartialEq for TryAcquireError

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for TryAcquireError

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

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

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

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