Description
I couldn't figure out how to minimize the code itself, but the exact same crate compiles successfully with incremental compilation disabled (by setting CARGO_INCREMENTAL=0) and fails with incremental compilation enabled. Running cargo clean also gets incremental compilation working again
Code
This looked like the function originally identified in the stack trace:
use camino::Utf8PathBuf;
use futures::prelude::*;
use miette::{IntoDiagnostic, WrapErr};
use tokio::sync::mpsc;
use tracing::{debug, trace, error, info, instrument};
use evdev_async::{AsyncDevice, InputEvent, KeyEvent};
use crate::{supervisor::Shutdown, dispatcher::Event};
#[instrument(skip(stop))]
pub async fn watch(path: Utf8PathBuf, dispatch_tx: mpsc::Sender<Event>, mut stop: Shutdown) -> miette::Result<()> {
let mut device = AsyncDevice::new(&path)
.into_diagnostic()
.wrap_err_with(|| format!("could not open evdev device {}", path))?;
info!(%path, "Watching input device");
loop {
tokio::select! {
_ = stop.shutdown() => {
debug!("Shutting down watcher loop");
break;
},
event = device.next() => {
match event {
Some(Ok(ev)) => {
let event = InputEvent::from(ev);
trace!(?event, "Received input event");
if let InputEvent::Key(ev) = event {
let dispatch_event = match ev {
KeyEvent::Press(code) => Event::KeyPress(code),
KeyEvent::Release(code) => Event::KeyRelease(code),
};
dispatch_tx.send(dispatch_event).await
.into_diagnostic()
.wrap_err("dispatcher closed")?;
}
},
Some(Err(err)) => {
error!(?err, "Failure reading input events");
},
None => {
info!("Input device has closed");
break;
},
}
}
}
}
Ok(())
}Meta
