    Interface ReadSession<Format>

    Public-facing read session interface.

    Yields records directly (as an async iterable or ReadableStream) and translates transport errors into thrown exceptions. Track progress using ReadSession.nextReadPosition / ReadSession.lastObservedTail.

    const session = await stream.readSession({
      start: { from: { tailOffset: 50 } },
      stop: { wait: 15 },
    });

    for await (const record of session) {
      console.log(record.seqNum, record.body);
    }
    interface ReadSession<Format extends "string" | "bytes" = "string"> {
        locked: boolean;
        "[asyncDispose]"(): PromiseLike<void>;
        "[asyncIterator]"(): AsyncIterator<ReadRecord<Format>, any, any>;
        cancel(reason?: any): Promise<void>;
        getReader(options: { mode: "byob" }): ReadableStreamBYOBReader;
        getReader(): ReadableStreamDefaultReader<ReadRecord<Format>>;
        getReader(
            options?: ReadableStreamGetReaderOptions,
        ): ReadableStreamReader<ReadRecord<Format>>;
        lastObservedTail(): StreamPosition;
        nextReadPosition(): StreamPosition;
        pipeThrough<T>(
            transform: ReadableWritablePair<T, ReadRecord<Format>>,
            options?: StreamPipeOptions,
        ): ReadableStream<T>;
        pipeTo(
            destination: WritableStream<ReadRecord<Format>>,
            options?: StreamPipeOptions,
        ): Promise<void>;
        tee(): [
            ReadableStream<ReadRecord<Format>>,
            ReadableStream<ReadRecord<Format>>,
        ];
    }
