Struct ArchetypeLayout 

pub struct ArchetypeLayout { /* private fields */ }

Sorted set of TypeIds identifying which components an archetype holds.

Two layouts with the same type set (regardless of input order) are equal and hash the same.

Implementations

impl ArchetypeLayout

pub fn from_type_ids(ids: &[TypeId]) -> Self

Create a layout from an unsorted, possibly-duplicate slice of type IDs.

pub fn empty() -> Self

Create an empty layout (the “void” archetype for entities with no components).

pub fn contains(&self, id: TypeId) -> bool

Whether this layout contains the given type.

pub fn with_added(&self, id: TypeId) -> Self

Return a new layout with id added (no-op if already present).

pub fn with_removed(&self, id: TypeId) -> Self

Return a new layout with id removed (no-op if absent).

pub fn len(&self) -> usize

The number of component types in this layout.

pub fn is_empty(&self) -> bool

Whether this layout has zero component types.

pub fn iter(&self) -> impl Iterator<Item = TypeId> + '_

Iterate the type IDs in sorted order.
