Struct Counter

pub struct Counter { /* private fields */ }

Globally available counter with a defined target.

Implementations

impl Counter

pub fn new(from: usize, target: usize) -> Self

Create a Counter starting at from with target.

pub fn to(target: usize) -> Self

Create a Counter starting at 0 with target.

pub fn value(&self) -> usize

Fetch the current Counter value.

pub fn target(&self) -> usize

Fetch the target Counter value.

pub fn set(&self, rhs: usize)

Inner function setting the Counter value and waking a waker if any.

Operator = has no backing trait, thus this method must be exposed directly.

Trait Implementations

impl Add<usize> for Counter

type Output = Counter

The resulting type after applying the + operator.

fn add(self, rhs: usize) -> Self::Output

Performs the + operation.

impl AddAssign<usize> for Counter

fn add_assign(&mut self, rhs: usize)

Performs the += operation.

impl Clone for Counter

fn clone(&self) -> Counter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Counter

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

Formats the value using the given formatter.

impl Future for Counter

type Output = usize

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.

impl Sub<usize> for Counter

type Output = Counter

The resulting type after applying the - operator.

fn sub(self, rhs: usize) -> Self::Output

Performs the - operation.

impl SubAssign<usize> for Counter

fn sub_assign(&mut self, rhs: usize)

Performs the -= operation.
