Replaying Events

IH-Muse allows you to replay previously recorded events from a file. This is useful for testing, simulating system behavior, or reprocessing historical data.

Using the Replayer

To replay events, use the replay method of the Muse client.

await muse.replay("events.bin")

use std::path::Path;

muse.replay(Path::new("events.bin")).await?;

Note: Ensure that the serialization format of the recording file matches the expected format (based on the file extension).

Command-Line Interface

You can also use the command-line interface (CLI) tool to replay events.

Replaying with the CLI

ih-muse-cli replay --input events.bin --poet-url http://localhost:8000

CLI Options

  • --input: Path to the recording file.

  • --poet-url: URL of the Muse system endpoint (defaults to http://localhost:8000).

Example:

ih-muse-cli replay --input events.json --poet-url http://localhost:8000

This command will replay the events from events.json to the specified Muse system.

Handling Serialization Formats

The CLI tool automatically determines the serialization format based on the file extension:

  • .bin for Bincode serialization

  • .json for JSON serialization

Ensure your recording files have the correct extension to avoid errors during replay.
