Struct TickCallbackRegistry 

pub struct TickCallbackRegistry { /* private fields */ }

Registry of mode-contributed per-tick drain closures.

Stored behind an Arc and shared by reference: the host calls run_all once per tick; modes register during Mode::on_activate and unregister via the returned TickCallbackRegistration token’s Drop.

Implementations

impl TickCallbackRegistry

pub fn new() -> Self

Construct an empty registry.

pub fn register( self: &Arc<Self>, callback: TickCallback, ) -> TickCallbackRegistration

Register a per-tick drain closure. Returns an RAII registration token; dropping it removes the closure. Modes accumulate the token in their Guard so deactivation drops it and the per-tick drain stops naturally.

pub fn run_all(&self) -> Vec<Effect>

Run every registered callback once, in registration order, and return the concatenated Effects for the host to apply. Called once per editor tick from Editor::run_tick_pending.

Holds the lock for the duration: a callback MUST NOT call register / drop a TickCallbackRegistration on this same registry from inside its body (it would deadlock). Drain closures only ever touch their own channel + return effects, so this is a documented non-constraint in practice.

Trait Implementations

impl Debug for TickCallbackRegistry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TickCallbackRegistry

fn default() -> Self

Returns the “default value” for a type.
