Trait bevy::ecs::storage::SparseSetIndex

pub trait SparseSetIndex: Clone + PartialEq + Eq + Hash {
    // Required methods
    fn sparse_set_index(&self) -> usize;
    fn get_sparse_set_index(value: usize) -> Self;
}

Represents something that can be stored in a SparseSet as an integer.

Ideally, the usize values should be very small (ie: incremented starting from zero), as the number of bits needed to represent a SparseSetIndex in a FixedBitSet is proportional to the value of those usize.

Required Methods

fn sparse_set_index(&self) -> usize

Gets the sparse set index corresponding to this instance.

fn get_sparse_set_index(value: usize) -> Self

Creates a new instance of this type with the specified index.

Object Safety

This trait is not object safe.
