CreateResourceGate

Allocate a fresh ResourceGateId — a per-handle mutual-exclusion slot with a FIFO waiter queue. A checkout-style stdlib module (sqlite, kv, proc, pty, serial, stream) creates one gate per resource handle when the handle is opened, then acquires it via WaitKind::ResourceSlot before each offloaded op and releases it via RuntimeRequest::ReleaseResourceGate when the op completes. The continuation receives RuntimeResponse::ResourceGate.

Fields

continuation: Box<dyn NativeContinuation>

ReleaseResourceGate

Release ownership of a previously-acquired resource gate, waking the FIFO head waiter (if any) so exactly one queued acquirer proceeds. The continuation resumes with RuntimeResponse::Value(nil).

Fields

gate: ResourceGateId

continuation: Box<dyn NativeContinuation>

CloseResourceGate

Close a resource gate: fail every parked waiter with a structured “gate closed” error and drop the gate record. Used when a handle is closed/tombstoned so queued acquirers fail fast rather than hang.

Fields

gate: ResourceGateId

continuation: Box<dyn NativeContinuation>
