frust-devtools

The in-app debug service a Frust app hosts for external tooling. It listens on an ephemeral loopback TCP port (127.0.0.1 only), speaks the NDJSON JSON-RPC protocol defined by frust-devtools-protocol, and answers every request through one trait, DevtoolsBackend, which a shell implements. The service mints a random per-process token, prints it on a discovery line, and requires it at handshake before any other method is served.

The tooling side (frust-drive, frust-tui) does not depend on this crate; both sides meet at frust-devtools-protocol. The only Frust crate this one depends on is that protocol crate.

Applications do not depend on this crate directly. The platform shells embed it behind their devtools feature, which is meant for debug and profile builds.

let devtools = Service::start(ShellBackend, AppInfo::new("my-app", "0.1.0"))?;
// ...each frame, from the frame hook (never blocks):
// devtools.publish_frame_stats(stats);
devtools.shutdown();

ShellBackend is a type implementing DevtoolsBackend; see the crate documentation for a complete example.
