Struct evenio::archetype::Archetype

pub struct Archetype { /* private fields */ }

A container for all entities with a particular set of components.

Each component has a corresponding columnm of contiguous data in this archetype. Each row in is then a separate entity.

For instance, an archetype with component set {A, B, C} might look like:

Entity ID	Column A	Column B	Column C
Entity 0	“foo”	123	true
Entity 1	“bar”	456	false
Entity 2	“baz”	789	true

Implementations

impl Archetype

pub fn index(&self) -> ArchetypeIdx

Returns the index of this archetype.

pub fn entity_count(&self) -> u32

Returns the total number of entities in this archetype.

pub fn entity_ids(&self) -> &[EntityId]

Returns a slice of EntityIds for all the entities in this archetype.

pub fn component_indices(&self) -> &[ComponentIdx]

Returns a sorted slice of component types for every column in this archetype.

The returned slice has the same length as the slice returned by columns.

pub fn columns(&self) -> &[Column]

Returns a slice of columns sorted by ComponentIdx.

pub fn column_of(&self, idx: ComponentIdx) -> Option<&Column>

Finds the column with the given component. Returns None if it doesn’t exist.
