QUESTION
I am trying to run a CentOS 8 server through VirtualBox (6.1.30) (Vagrant), which worked just fine yesterday for me, but today I tried running a sudo yum update
. I keep getting this error for some reason:

QUESTION
Studying Go generics, I'm running into an error I can't seem to untangle. I've boiled it down to the simplest code:
...ANSWER
Answered 2022-Feb-26 at 06:13because you want
t = append(t, 0)
the data type can be int or float group.
this code should work
QUESTION
Now that type parameters are available on golang/go:master
, I decided to give it a try. It seems that I'm running into a limitation I could not find in the Type Parameters Proposal. (Or I must have missed it).
I want to write a function which returns a slice of values of a generic type with the constraint of an interface type. If the passed type is an implementation with a pointer receiver, how can we instantiate it?

There is probably a better way—this one seems a bit clumsy—but I was able to work around this with reflect

QUESTION
I can't run any Xcode Swift Playground project without getting the error:
Failed to launch process. Failed to attach to stub for playground execution: error: attach failed ((os/kern) invalid argument)
Does anyone know how to solve this?
...ANSWER
Answered 2021-Nov-11 at 09:56I've the same issue. If I launch Xcode using rosetta, it doesn't show anything. You must switch off rosetta and it works perfect.

QUESTION
In the documentation for Ord
, it says
Implementations must be consistent with the PartialOrd implementation [...]
That of course makes sense and can easily be archived as in the example further down:

Answered 2021-Dec-26 at 00:40Apparently, there is a reference to that, in a github issue - rust-lang/rust#63104:
This conflicts with the existing blanket impl in core.
QUESTION
What is the difference between Arrow Functions and Regular Functions in implementing Interfaces, so that code A causes compile-time error and code B compiles successfully.
Note: in tsconfig.json
all strict type-checking options are enabled, including strictFunctionTypes
, BTW it supposed that by enabling strict
all strict type-checking options get enabled.
Code A that causes compile time error
...ANSWER
Answered 2021-Dec-08 at 15:28With --strictFunctionTypes
enabled, function types' parameters are checked contravariantly, as required to maintain type safety:
QUESTION
In my program source code I have the following function (Promise concurrency limitation function, similar to pLimit):
...ANSWER
Answered 2021-Nov-26 at 13:37You have await
inside async function. This works roughly as follows:
- Execute code line by line until
await
keyword - Pause execution of this code block
- Once awaited value resolved continue until next
await
keyword
In your case, it iterates 20 times, then pauses everything once you hit a limit. Then, once at least one promise inside ret
resolved it proceeds.
Next thing that is happening is that once any of the promises resolved, removes itself from array. But since almost everything happens instantaneously, you see that it - resolves all 20 promises, fills with another 20. If you make your iteratorFn
slower with random delays, you'll see, that pool is constantly filling up to 20 and then almost immediately replaces freed space in pool with new promise, while there is at least some elements left.
Let's replace your iteratorFn
with this and call it:
QUESTION
I've been trying to find documentation on how Rust resolves trait blanket implementations in case module boundaries are involved, but didn't find much directly related to it.
Let's consider an example with two similar, but slightly different code snippets:
The first one is code that does compile just fine, but suffers an infinite runtime recursion. This happens because the blanket implementation of the ClonableIterator
for T: Iterator+Clone
matches against the Box>
which is, thanks to our manual implementation of Clone
and Box
's blanket implementation of Iterator
now Iterator+Clone
.
ANSWER
Answered 2021-Dec-05 at 01:10I don't have a complete citation of the reference manual for all the parts here, but the difference I see between these two cases is ClonableIterator
is not visible in mod helper
(there is no use super::ClonableIterator
). Thus, the trait is not consulted for arbitrary types when looking up methods, but (evidently) it is for dyn super::ClonableIterator
, presumably because it would be gratuitously unhelpful to not do that.
So the method lookup procedure will be doing approximately this:
- We start with
*self
, an explicit dereference of&Box>
of typeBox>
.- Does this have an inherent method named
box_clone()
? No. - Does any visible trait have a method named
box_clone()
?- In the first program, yes (
ClonableIterator
was declared in the same scope), so that one is called. - In the second program, no, so continue.
- In the first program, yes (
- Does this have an inherent method named
- Dereference
Box>
to obtaindyn CloneableIterator<'a>
.- Does this have an inherent method named
box_clone()
? No. - Does any visible trait have a method named
box_clone()
? Yes, apparentlyCloneableIterator
is visible for thedyn
type unconditionally.
- Does this have an inherent method named
QUESTION
Please have a look at the following little demo:
- Function
f
should accept ONE pair of the form ['stringX', 'stringXstringX'] (-> this is working) - But function
g
should accept A VARIABLE NUMBER of pairs of this pattern. How do I have to type functiong
to make this happen?
