fn sparse_set_index(&self) -> usize;
fn get_sparse_set_index(value: usize) -> Self;
}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.
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.
