SignalAsync<TPayload>(string, string, TPayload, CancellationToken)

Delivers a typed signal to whichever instance is waiting on name and correlationId, and returns whether one was.

ValueTask<bool> SignalAsync<TPayload>(string name, string correlationId, TPayload payload, CancellationToken ct = default)

Parameters

name string

correlationId string

payload TPayload

ct CancellationToken

Returns

ValueTask<bool>

Type Parameters

TPayload

Remarks

The payload type is declared by the definition, so a mismatch is a compile-time error rather than a runtime surprise. It travels as JSON, which keeps webhook and cross-language senders possible — the typed binder is applied on the engine's side of that boundary.

Delivery is at-most-once: the bookmark is consumed atomically, so two concurrent senders cannot both resume the same wait, and the second gets false.

SignalAsync(string, string, string?, CancellationToken)

Delivers a signal whose payload is already JSON — the escape hatch for webhooks and senders outside this process (§11.5).

ValueTask<bool> SignalAsync(string name, string correlationId, string? payloadJson, CancellationToken ct = default)

Parameters

name string

correlationId string

payloadJson string

ct CancellationToken

Returns

ValueTask<bool>
