Struct raii_counter::Counter

pub struct Counter { /* fields omitted */ }

Essentially an AtomicUsize that is clonable and whose count is based on the number of copies. The count is automatically updated on Drop.

Methods

impl Counter

pub fn new() -> Counter

pub fn new_with_size(size: usize) -> Counter

pub fn downgrade(self) -> WeakCounter

Consume self (causing the count to decrease by 1) and return a weak reference to the count through a WeakCounter

pub fn count(&self) -> usize

This method is inherently racey. Assume the count will have changed once the value is observed.

Trait Implementations

impl Clone for Counter

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Drop for Counter

fn drop(&mut self)

Executes the destructor for this type.
