Trait InputCounter 

pub trait InputCounter:

    + Sync
    + 'static {
    type Tracker: InputCounterTracker;

    // Required methods
    fn increment(&self) -> Self::Tracker;
    fn decrement(&self);
}

A counter used by CountInput to track total and concurrent inputs.

Contract:

• increment is called exactly once per input and returns the tracker inserted into extensions
• decrement is called exactly once when the input is finished

Required Associated Types

type Tracker: InputCounterTracker

Tracker that will be inserted into the input extensions.

Required Methods

fn increment(&self) -> Self::Tracker

Registers a new in flight input and returns a tracker for that input.

fn decrement(&self)

Marks the end of an in flight input.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
