Required methods

fn init(&self)

Initializes the entity filter for iteration.

fn filters(
    &self
) -> (&Self::ArchetypeFilter, &Self::ChunksetFilter, &Self::ChunkFilter)

Gets mutable references to both inner filters.

fn into_filters(
    self
) -> (Self::ArchetypeFilter, Self::ChunksetFilter, Self::ChunkFilter)

Converts self into both inner filters.

fn iter_archetype_indexes<'a, 'b>(
    &'a self,
    storage: &'b Storage
) -> FilterArchIter<'b, 'a, Self::ArchetypeFilter>

Gets an iterator over all matching archetype indexes.

fn iter_chunkset_indexes<'a, 'b>(
    &'a self,
    archetype: &'b ArchetypeData
) -> FilterChunkIter<'b, 'a, Self::ChunksetFilter>

Gets an iterator over all matching chunkset indexes.

fn iter<'a, 'b>(
    &'a self,
    storage: &'b Storage
) -> FilterEntityIter<'b, 'a, Self::ArchetypeFilter, Self::ChunksetFilter>
