Trait ResourceCounterContext

pub trait ResourceCounterContext<R, T>: CounterContext<T> {
    // Required method
    fn with_per_resource_counters<O, F: FnOnce(&T) -> O>(
        &mut self,
        resource: &R,
        cb: F,
    ) -> O;

    // Provided method
    fn increment<F: Fn(&T) -> &Counter>(&mut self, resource: &R, cb: F) { ... }
}

A context that provides access to per-resource counters for observation and debugging.

Required Methods

fn with_per_resource_counters<O, F: FnOnce(&T) -> O>( &mut self, resource: &R, cb: F, ) -> O

Call cb with an immutable reference to the set of counters on resource.

Provided Methods

fn increment<F: Fn(&T) -> &Counter>(&mut self, resource: &R, cb: F)

Increments both the per-resource and stackwide versions of the counter returned by the callback.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
