Module worker 

Generic rebuild-worker driver for dev servers.

Spawns a background OS thread that owns the rebuild loop:

1. Block waiting for a tick.
2. Drain any extra ticks queued before the thread woke up — they coalesce into a single rebuild.
3. Run the user-supplied rebuild closure.
4. Drain any ticks that arrived during the rebuild — if any did, re-tick ourselves so the next iteration runs without waiting.
5. Report success / error via RebuildReporter and broadcast the corresponding live-reload event.

The closure is the only thing that varies between consumers (webui-cli builds and renders an app, webui-press rebuilds a docs site). It returns Result<Vec<String>, RebuildError>: the Ok value is a list of plain advisory lines to print under the rebuild line, and the Err lets the worker print a terminal rendering and broadcast a plain one to browsers.

Structs

RebuildError

Failure returned by a rebuild closure.

RebuildWorker

Owns a rebuild thread. Keep this handle alive for the server’s lifetime.

Functions

spawn_rebuild_worker

Spawn the rebuild worker on a dedicated OS thread and return the owned handle used to shut it down. The watcher closure should call tx.try_send(paths) with the changed paths for every filesystem event burst — failed sends (channel full) are intentional coalescing. Obtain tx via RebuildWorker::sender.

Type Aliases

TickSender

Tick sender given to the watcher closure. Cheap to clone.
