A small and fast async runtime. This crate simply re-exports other smaller async crates (see the source). To use tokio-based libraries with smol, apply the async-compat adapter to futures and I/O types.

QUESTION
I'm trying to implement an async read wrapper that will add read timeout functionality. The objective is that the API is plain AsyncRead
. In other words, I don't want to add io.read(buf).timeout(t) everywehere in the code. Instead, the read instance itself should return the appropriate io::ErrorKind::TimedOut
after the given timeout expires.
I can't poll the delay
to Ready though. It's always Pending. I've tried with async-std
, futures
, smol-timeout
- the same result. While the timeout does trigger when awaited, it just doesn't when polled. I know timeouts aren't easy. Something needs to wake it up. What am I doing wrong? How to pull this through?
ANSWER
Answered 2022-Feb-08 at 19:32Async timeouts work as follows:
- You create the timeout future.
- The runtime calls
poll
into the timeout, it checks whether the timeout has expired. - If it is expired, it returns
Ready
and done. - If it is not expired, it somehow registers a callback for when the right time has passed it calls
cx.waker().wake()
, or similar. - When the time has passed, the callback from #4 is invoked, that calls
wake()
in the proper waker, which instructs the runtime to callpoll
again. - This time
poll
will returnReady
. Done!
The problem with your code is that you create the delay from inside the poll()
implementation: self.expired = delay(self.timeout);
. But then you return Pending
without polling the timeout even once. This way, there is no callback registered anywhere that would call the Waker
. No waker, no timeout.
I see several solutions:
A. Do not initialize PrudentIo::expired
to None
but create the timeout
directly in the constructor. That way the timeout will always be polled before the io
at least once, and it will be woken. But you will create a timeout always, even if it is not actually needed.
B. When creating the timeout
do a recursive poll:

I have this 'wake up' command for my bot which is supposed to move the metnioned member between 2 specific voice chats and afterwards move them back to their original vc. I managed to get the bot to move me between those 2 vc's but I have no idea how to check in which vc the user was before nmoving. I tried searching online and going through the documentation but I can't figure it out. Here's my code:

Answered 2021-Dec-03 at 16:37You can bind the key_press
of F1
to the creation of a DelayTimer
which will
execute the various tasks you need after a defined duration has passed.
The following code will create a separate timer every time the F1
key is pressed. Every scheduled task will print a line after 2000, 39999 and 50000 ms. Since it is not specified, with this solution it is possible that two instances of the created task runs at the same time.

QUESTION
i was looking for a way to make the cog executes a function withing the cog when it's loaded/reloaded but i found no such function or anyone talking about it,
so i came up with the INGENIOUS idea of trying to use a string to call a function within the cog.
i tried couple of things, mainly a combination of eval
and getattr
but i was unsuccessful to get a working code coz... brain too smol.
hope this will clear the idea of what i want to do:
cog test.py
ANSWER
Answered 2021-Aug-30 at 03:13Since Discord Cog is a class, an __init__
method can be called upon, which will be executed upon initialisation. I have a similar setup whereby, whenever a Cog is loaded/reloaded, a set of instructions are performed.

QUESTION
In an attempt to create a function using Swift's Measurements which returns a Double. I apparently am smol brained and can't figure out why, even though my function is calling to return a double, it is giving me an error of the following :
Cannot convert return expression of type 'Measurement' to return type 'Double'
ANSWER
Answered 2021-May-30 at 21:39The issue is that addUpCentimeters is a measurement unit, not a double. You therefore have two options, either you return that unit, or you call addUpCentimeters.value to get the actual double value.

QUESTION
Im developing an API in php, and i ran into a problem, basically http_response_code(int $code);
behaviour is unpredictable, it just always gets sent at all costs if present anywhere in the code, and after that, naturally i cannot set another http_response_code(int $otherCode)
as headers are already sent. I do not know what i am doing wrong, but i think i can boldly assume that http_response_code(int $code);
can be used conditionally because it makes all the sense for me.
My question is, how this problem should be solved? I have to use the correct response codes, is there a working alternative which does not use rng to decide if it obeys an if statement?
