Trait RollingCounter 

pub trait RollingCounter {
    type NonAtomic;

    const DEFAULT: Self;

    // Required method
    fn next(&self) -> Self::NonAtomic;
}

A trait for types that can be used as rolling counters. It is only intended for the atomic counterparts to Identifier types.

Required Associated Constants

const DEFAULT: Self

The starting value of the rolling counter.

Required Associated Types

type NonAtomic

The non-atomic identifier type associated with this atomic type.

Required Methods

fn next(&self) -> Self::NonAtomic

Atomically increments the value and returns the previous value.

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.
