Trait 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.

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.
