I think this'll want to be the AbortOnDrop handle (or something like that name) Pat recently added too

Here I'd recommend using AsyncWriteExt::write_all since it'll bundle all this internally

This'll need some special handling to ensure that if this is cancelled that the task isn't forgotten

elliottt opened PR #6928 from elliottt:trevor/socket-changes to bytecodealliance:pch/backpressure_2:

Spawn a task if we can't immediately satisfy a write, storing its join handle for later. Use the presence of the join handle to decide when writes are ready, or if a flush has completed.

Ah you're right, I should only clear the option if the write task has finished.

This may be preexisting, but I think this means that I/O errors turn into trapping errors? Or at least I think that the Err here gets turned into a trap, but I could easily be misremembering

From a DM: we'll have to use try_write in a loop as tokio doesn't allow write_all with a non-mutable reference for self.

The error handling scheme gets fixed in my branch to explicitly call out operation failed vs traps.

I've rebased on Pat's branch, and reworked the error handling to categorize error results as traps or runtime errors.
