Struct DerivedCache

Source

pub(super) struct DerivedCache {
    generation: u64,
    current: FxHashMap<TypeId, Arc<dyn Any + Send + Sync>>,
    prev: FxHashMap<TypeId, Arc<dyn Any + Send + Sync>>,
}

Expand description

The previous generation’s values stick around (prev) so incremental builders can extend them instead of starting over; a value is consumed (removed) the first time its type resolves under the new generation, and anything never consumed drops on the following generation change.
