CounterHandler

public protocol CounterHandler : AnyObject

A CounterHandler represents a backend implementation of a Counter.

This type is an implementation detail and should not be used directly, unless implementing your own metrics backend. To use the SwiftMetrics API, please refer to the documentation of Counter.

Implementation requirements

To implement your own CounterHandler you should respect a few requirements that are necessary so applications work as expected regardless of the selected CounterHandler implementation.

The CounterHandler must be a class.
