AsyncFileDialog blocks on Windows about rfd HOT 5 OPEN

In fact, even AsyncFileDialog is block, .await means the task will blocked until it complete

to solve it, I think you should spawn another task to call AsyncFileDialog , and let your main loop check whether it is completed.

from rfd.

Yes, but in the current code, the thread that the executor is running on is blocked, because the future blocks when polled. This means that no other futures can be executed while the file dialog is open, and if the executor is running on the main thread, the application itself will freeze. That's what I'm fixing.

That's not how Futures work in Rust. When you await a future, it doesn't block the thread; it causes the task to "yield" (within whatever executor you're using, it'll move on to the next task to be executed, and probably won't poll that future again until the task is awoken).

@valadaptive I mean, the thread won't be blocked, but the task will be blocked, even it's async
