wsmirror is a simple server application that lets you run Websocket echo server for playing with WebSockets and testing WebSocket client implementations.

It should work similar to like echo.websocket.org worked before.

• ws://ws.vi-server.org/mirror , wss://ws.vi-server.org/mirror
• ws://vi-server.org:1939/

Usage: wsmirror <tcp_bind_socket_address>

Specify socket address like 127.0.0.1:1234 or [::]:8080 as a sole command line argument.
Other options, such as maximum number of simultaneous clients, are configurable only in source code constants.

If you build the crate with metrics feature (not default) and set PROMETHEUS_EXPORT_ADDR environment variable to e.g. 127.0.0.1:1235 then Prometheus metrics would be exported on http://127.0.0.1:1235/metrics.
