Describe the bug

Originally, @asvetlov intended to delete any use of attrs from aiohttp 4.0+ series via aio-libs/aiohttp#5284. He dropped it from the runtime deps too.

But there are some places that still rely on attrs meaning that this will cause failures in runtime because of the missing dep. The tests currently succeed because attrs is listed as a test dep.

Since this comes up so often my plan is to introduce a new quit_app key-binding that only reacts if no popup is open.

For reference: #770 , #766

this means:

• in popups there is still exit_popup (ESC) to close it which allows closing text input popups that otherwise collide with q-key
• we still have exit (CTRL+C) that exits the app no matter in what place
• the new quit_app (Q

Stitching API

Opencv provide a Stitching module/API

Bascially, i would like to be able to rewrite stitching_detailed.cpp in javascript

This includes :

• Stitcher class
• Features extractors (already implemented in opencv4nodejs)
• Estimator

Is it possible for sqlx to have an impl of Decode for Cow<'_, str> (with implementation delegation to str, similar to what String is doing)?

What should happen if deliver_cancel raises an exception? In the current implementation, the shielded cancel scope will prevent it from propagating until the process exits, which might take a while if the crash occurred before signaling the process in any way. Maybe on exception from a user-specified deliver_cancel we should call the default deliver_cancel to kill the process? Or just kill() since
