Expand description
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
fn sparse_set_index(&self) -> usize
Gets the sparse set index corresponding to this instance.
fn get_sparse_set_index(value: usize) -> Self
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.
