Trait FixedSize 

pub trait FixedSize: Value + PartialEq {
    const SIZE: u16;
    const INVALID: Self;
}

This trait marks points with a fixed size. All non-string values are actually fixed size.

Required Associated Constants

const SIZE: u16

The size of this value

const INVALID: Self

The value when the point is not supported

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.
