Fields

trace_channel: ChannelTraceFn

Emit one GcEdge::Value per value the channel’s buffer holds (with exact multiplicity — each is one strong Rc the registry owns). false aborts the pass (the registry RefCell was unavailable).

sever_channel: fn(ChannelId) -> Vec<Value>

Drain the channel’s buffer, returning its contents for deferred drop.

evict_channel: fn(ChannelId)

Remove a channel record whose handle is gone (only if it has no parked senders/receivers — a waiter keeps the record until the task is reaped).

trace_promise: PromiseTraceFn

Emit the promise’s settled value, if any, as a GcEdge::Value.

sever_promise: fn(PromiseId) -> Vec<Value>

Clear the promise’s settled value, returning it for deferred drop.

evict_promise: fn(PromiseId)

Remove a settled promise record whose handle is gone (only if it has no waiters).
