Trait components_arena::ComponentId

pub trait ComponentId: Debug + Copy + Eq + Ord + Hash + Send + Sync {
    fn from_raw(raw: (usize, NonZeroUsize)) -> Self;
    fn into_raw(self) -> (usize, NonZeroUsize);
}

An implementer of the ComponentId trait is a type behaves as Id.

Required Methods

fn from_raw(raw: (usize, NonZeroUsize)) -> Self

Forms an id from the into_raw function result.

fn into_raw(self) -> (usize, NonZeroUsize)

Transforms the id to primitive-typed parts, which can be easily passed through FFI and stored in non-generic context.

Use from_raw to get the source id back.
