Struct PendingCount 

pub struct PendingCount(/* private fields */);

Atomic counter for pending requests on a backend

Implementations

impl PendingCount

pub fn new() -> Self

Create a new pending count initialized to zero

pub fn increment(&self)

Increment the pending count

pub fn try_increment_from(&self, observed: usize) -> bool

Increment the pending count only if it still matches the observed value.

pub fn decrement(&self)

Decrement the pending count

pub fn get(&self) -> usize

Get the current pending count

Trait Implementations

impl AsRef<Arc<Atomic<usize>>> for PendingCount

fn as_ref(&self) -> &Arc<AtomicUsize>

impl Clone for PendingCount

fn clone(&self) -> PendingCount

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PendingCount

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

Formats the value using the given formatter.

impl Default for PendingCount

fn default() -> Self

Returns the “default value” for a type.

impl Deref for PendingCount

type Target = Arc<Atomic<usize>>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for PendingCount

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

Formats the value using the given formatter.

impl Eq for PendingCount
