Type parameters​

NameDefaultDescription
Tvoidthe channel message type

The maximum amount of messages the Channel can buffer. If 0, the channel is unbuffered and the communication is synchronous.

Definition​

get capacity(): number;

isExhausted​

Returns true if the channel is closed and there are no message in the buffer (length = 0), false otherwise.

Definition​

get isExhausted(): boolean;

length​

The amount of messages currently in the read buffer.

Definition​

get length(): number;

Methods​

asyncStream​

Returns an asynchronous stream of values.

Definition​

asyncStream(): AsyncStream<T>;

Overrides​

AsyncStreamable.asyncStream

readable​

Returns the Channel as a readonly Channel.Read instance.

Definition​

readable(): Channel.Read<T>;

receive​

Returns the next message sent to the Channel. Blocks if there are no messages.

      signal?: AbortSignal | undefined;
      timeoutMs?: number | undefined;
      recover: (channelError: Channel.Error) => RT;
    }): Promise<T | RT>;
