    fn inc(self) -> Self { ... }
}

A trait describing “newtypes” that wrap an integer.

Required Associated Types

type Rep

type Atomic

Required Methods

fn new(val: Self::Rep) -> Self

fn from_usize(index: usize) -> Self

fn index(self) -> usize

fn rep(self) -> Self::Rep

Provided Methods

fn inc(self) -> Self

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.
