Description
Adds a new Rust WebSocket example demonstrating real-time bidirectional communication on Vercel's Rust runtime.
The example serves an Axum router behind
VercelLayerwith two routes:GET /— an interactive HTML client (embedded viainclude_str!) with a connection status indicator and live message log.GET /ws— the WebSocket endpoint. The handler upgrades the connection and runs two concurrent tasks over a single writer:tickevent to the client every second (server-initiated), andA single writer task owns the
SplitSinkand is fed by anmpscchannel, so both loops can send frames without sharing the non-clonable sink. All server messages are JSON tagged with atypefield (welcome,echo,tick).Also adds
