Struct raii_counter::WeakCounter

pub struct WeakCounter(_);

A 'weak' Counter that does not affect the count.

Methods

impl WeakCounter

pub fn new() -> WeakCounter

pub fn count(&self) -> usize

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

pub fn upgrade(self) -> Counter

Consumes self, becomes a Counter

pub fn spawn_upgrade(&self) -> Counter

Instead of clone + upgrade, this will only clone once Defaults to a Counter of size 1

pub fn spawn_upgrade_with_size(&self, size: usize) -> Counter

Instead of clone + upgrade, this will only clone once

Trait Implementations

impl Clone for WeakCounter

fn clone(&self) -> WeakCounter

Returns a copy of the value.

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

Performs copy-assignment from source.
