Trait Index 

pub trait Index:
    TryFrom<usize>
    + TryInto<usize>
    + Copy {
    const ZERO: Self;
}

An index type used for lookups into and out of arrays.

This is implemented so that Capts can use smaller index sizes (such as u32 or u16) for improved memory performance.

Required Associated Constants

const ZERO: Self

The zero index. This must be equal to (0usize).try_into().unwrap().

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.
