Struct OwnedSemaphorePermit 

pub struct OwnedSemaphorePermit { /* private fields */ }

Permits taken from a Semaphore held through an Arc. The release makes the progress SemaphorePermit’s does.

Implementations

impl OwnedSemaphorePermit

pub fn forget(self)

Keeps the permits out of the semaphore for good.

pub fn merge(&mut self, other: Self)

Merges other into this permit, so one drop returns both.

Panics

When the permits come from different semaphores, or their total overflows usize.

pub fn split(&mut self, n: usize) -> Option<Self>

Splits n permits off this one, or returns None when it holds fewer than n.

pub fn semaphore(&self) -> &Arc<Semaphore>

The semaphore these permits came from.

pub fn num_permits(&self) -> usize

How many permits this holds.

pub fn count(&self) -> usize

How many permits this holds; the same as num_permits.

Trait Implementations

impl Debug for OwnedSemaphorePermit

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

Formats the value using the given formatter.

impl Drop for OwnedSemaphorePermit

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
