Trait EntityRef

pub trait EntityRef: Copy + Eq {
    // Required methods
    fn new(_: usize) -> Self;
    fn index(self) -> usize;
}

A type wrapping a small integer index should implement EntityRef so it can be used as the key of an SecondaryMap or SparseMap.

Required Methods

fn new(_: usize) -> Self

Create a new entity reference from a small integer. This should crash if the requested index is not representable.

fn index(self) -> usize

Get the index that was used to create this entity reference.

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.
