Struct InstanceView 

pub struct InstanceView<'a> { /* private fields */ }

Read-only borrow of one instance’s state.

Implementations

impl<'a> InstanceView<'a>

pub fn id(&self) -> InstanceId

InstanceId of the viewed instance.

pub fn entity_count(&self) -> usize

Number of entities currently registered.

pub fn component_count(&self) -> usize

Total component count across all entities.

pub fn local_tick(&self) -> u64

Logical local tick of the instance.

pub fn entity_meta(&self, entity: EntityId) -> Option<&'a EntityMeta>

Per-entity metadata. None if the entity is not registered.

pub fn component( &self, entity: EntityId, type_code: TypeCode, ) -> Option<&'a Bytes>

Component bytes for an (entity, type_code) pair. None if the component is not attached to that entity.

pub fn entities(&self) -> impl Iterator<Item = (EntityId, &'a EntityMeta)> + 'a

Iterate every (entity, &meta) in ascending EntityId order (A23 canonical, supplied by BTreeMap iteration).

pub fn components_by_type( &self, type_code: TypeCode, ) -> impl Iterator<Item = (EntityId, &'a Bytes)> + 'a

Iterate every (entity, &bytes) whose component matches type_code. Useful for “list all posts” / “list all rolls” style queries without exposing the raw component map. Order: ascending EntityId (A23 canonical).
