Struct MutReceiver 

pub struct MutReceiver { /* private fields */ }

Per-user receiver that accumulates dirty bits for a single component and notifies the user’s [DirtySet] on first mutation.

Implementations

impl MutReceiver

pub fn new(diff_mask_length: u8) -> Self

Creates a MutReceiver with an atomic diff mask of diff_mask_length bytes.

pub fn attach_notifier(&self, notifier: DirtyNotifier)

Installed once per receiver by UserDiffHandler::register_component. Cheap no-op on re-attachment (OnceLock::set returns Err, ignored).

pub fn mask_snapshot(&self) -> DiffMask

Snapshot the receiver’s current mask into an owned DiffMask. Used by world_writer when copying the mask into sent_updates before clearing the receiver. Replaces the prior RwLockReadGuard<'_, DiffMask> API which forced callers to clone while holding a read lock.

pub fn mask_byte(&self, index: usize) -> u8

Read one byte of the receiver’s mask. Cheaper than mask_snapshot() when callers only need a single byte (currently unused but kept as the obvious primitive on top of the atomic representation).

pub fn diff_mask_is_clear(&self) -> bool

Returns true if no property bits are currently set in this receiver’s diff mask.

pub fn mutate(&self, property_index: u8)

Marks property_index dirty in the diff mask, notifying the dirty queue if the mask transitions from clean to dirty.

pub fn or_mask(&self, other_mask: &DiffMask)

ORs other_mask into the diff mask, notifying the dirty queue if the mask transitions from clean to dirty.

pub fn clear_mask(&self)

Clears all bits in the diff mask and notifies the dirty queue if the mask was dirty.

Trait Implementations

impl Clone for MutReceiver

fn clone(&self) -> MutReceiver

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
