Trait Length 

pub trait Length: Seal + Copy {
    const MAX: usize;
    const ZERO: Self;

    // Required methods
    fn from_usize(value: usize) -> Self;
    fn into_usize(self) -> usize;

    // Provided method
    unsafe fn add(self, amount: usize) -> Self { ... }
}

Required Associated Constants

const MAX: usize

const ZERO: Self

Required Methods

fn from_usize(value: usize) -> Self

fn into_usize(self) -> usize

Provided Methods

unsafe fn add(self, amount: usize) -> Self

Safety

The sum must fit this length representation and therefore usize.

Dyn Compatibility

This trait is not dyn compatible.

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