Dispatcher

Struct Dispatcher 

Source
pub struct Dispatcher(/* private fields */);
Expand description

First-class dispatcher (D21), cloneable handle over shared inner state. A graph binds one; the default is a thread-local singleton (D26).

Implementations§

Source§

impl Dispatcher

Source

pub fn new() -> Self

Creates or computes new.

Source

pub fn set_recording(&self, on: bool)

Turn the profile recorder on/off (D39). Off = near-zero invoke overhead.

Source

pub fn stat_for(&self, handle: Handle) -> Option<ProfileStat>

Read one handle’s accumulated counters.

Source

pub fn set_local_async_driver(&self, driver: Option<Rc<dyn LocalAsyncDriver>>)

Install or clear the graph-local async/time source driver (D111).

Source

pub fn local_async_driver(&self) -> Option<Rc<dyn LocalAsyncDriver>>

Read the installed local async/time source driver, if any.

Source

pub fn register(&self, f: NodeFn) -> Handle

Register a fn in the sync pool, returning its Handle (R-dispatch-all).

Source

pub fn register_async(&self, f: NodeFn) -> Handle

Register a fn in the LocalAsync pool (D20). The invoke is still sync void (R-sync-core) — the node’s async-pool kind drives the deferred-emit / pause buffering behavior, not the call mechanism.

Source

pub fn pool_kind(&self, pool_id: u32) -> PoolKind

The kind of a pool by id — the node reads this to decide async-paused buffering + per-invocation ctx snapshotting (R-pause-modes / R-async-paused).

Source

pub fn unregister(&self, handle: Handle)

Free a node’s fn slot (B32) — called from NodeInner::Drop. The pool stops holding a dropped node’s fn (and thus its captured upstream Cores) alive for the whole process. Idempotent / generation-checked: a stale unregister is a no-op.

Source

pub fn invoke(&self, handle: Handle, ctx: &Ctx)

Uniform sync-void invoke (R-sync-core / R-dispatch-all). Clones the fn out and drops the pool borrow before calling, so a nested downstream invoke triggered from inside the fn does not double-borrow the pool.
