Trait IndexedId 

pub trait IndexedId: Copy {
    const COUNT: usize;

    // Required methods
    unsafe fn from_index_release_unchecked(index: usize) -> Self;
    fn to_index(self) -> usize;
}

A trait for property-id-like types that can be stored compactly in an IdSet bitfield.

Required Associated Constants

const COUNT: usize

The number of distinct ids, i.e. the number of bits the set needs.

Required Methods

unsafe fn from_index_release_unchecked(index: usize) -> Self

Builds an id from its index in the set. The caller must guarantee that index < Self::COUNT.

fn to_index(self) -> usize

Returns the index of this id in the set.

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.

Implementors

impl IndexedId for LonghandId

const COUNT: usize = property_counts::LONGHANDS

impl IndexedId for PrioritaryPropertyId

const COUNT: usize = property_counts::PRIORITARY

impl IndexedId for NonCustomPropertyId

const COUNT: usize = property_counts::NON_CUSTOM
