Struct GlobalDiffHandler 

pub struct GlobalDiffHandler { /* private fields */ }

Global registry of mutation channels for every (entity, component) pair, used to fan out property changes to per-user dirty queues.

Implementations

impl GlobalDiffHandler

pub fn new() -> Self

Creates an empty GlobalDiffHandler.

pub fn kind_bit(&self, component_kind: &ComponentKind) -> Option<u16>

NetId of a registered kind, used as bit position in the per-user DirtyQueue’s flat-strided bitset. Returns None if the kind has never gone through register_component here.

pub fn kind_count(&self) -> u16

Highest kind_bit + 1 ever registered with this handler. The per-user DirtyQueue uses this to size its stride (ceil(kind_count / 64) AtomicU64 words per entity).

pub fn has_component( &self, global_entity: &GlobalEntity, component_kind: &ComponentKind, ) -> bool

Returns true if a mutation channel is registered for (global_entity, component_kind).

pub fn register_component( &mut self, component_kinds: &ComponentKinds, global_world_manager: &dyn GlobalWorldManagerType, global_entity: &GlobalEntity, component_kind: &ComponentKind, diff_mask_length: u8, ) -> MutSender

Creates a MutSender/MutReceiverBuilder pair for (global_entity, component_kind) and returns the sender.

pub fn deregister_component( &mut self, entity: &GlobalEntity, component_kind: &ComponentKind, )

Removes the mutation channel for (entity, component_kind), stopping further dirty notifications.

pub fn receiver( &self, address: &Option<SocketAddr>, entity: &GlobalEntity, component_kind: &ComponentKind, ) -> Option<MutReceiver>

Builds a MutReceiver for address from the builder registered for (entity, component_kind), if one exists.

Trait Implementations

impl Default for GlobalDiffHandler

fn default() -> Self

Returns the “default value” for a type.
