namespace N {

template
constexpr bool operator<(const T&, const T&) { return true; }
}
constexpr bool operator<(const N::A&, const N::A&) { return false; }
#include
int main() {
static_assert(std::less{}({}, {}), "assertion failed");
}
...ANSWER
Answered 2022-Mar-05 at 16:30What matters here is whether the unqualified lookup from inside std
finds any other operator<
(regardless of its signature!) before reaching the global namespace. That depends on what headers have been included (any standard library header may include any other), and it also depends on the language version since C++20 replaced many such operators with operator<=>
. Also, occasionally such things are respecified as hidden friends that are not found by unqualified lookup. It’s obviously unwise to rely on it in any case.

QUESTION
I have a problem using telebot API in python. If the user sends a message to the bot and waits for the response and at the same time he blocks the bot. I get this error and the bot will not respond for other users:
403,"description":"Forbidden: bot was blocked by the user
Try, catch block is not handling this error for me
any other idea to get rid of this situation? how to find out that the bot is blocked by the user and avoid replying to this message?
this is my code:
...ANSWER
Answered 2021-Aug-27 at 08:13This doesn't appear to actually be an error and thus try
catch
won't be able to handle it for you. You'll have to get the return code and handle it with if
else
statements probably (switch statements would work better in this case, but I don't think python has the syntax for it).
EDIT
Following the method calls here it looks like reply_to()
returns send_message()
, which returns a Message
object, which contains a json
string set to self.json
in the __init__()
method. In that string you can likely find the status code (400s and 500s you can catch and deal with as you need).

Unintended consequence of Mark Shannon's change that refactors fast opcode dispatching: https://github.com/python/cpython/commit/4958f5d69dd2bf86866c43491caf72f774ddec97 -- the INPLACE_ADD opcode no longer uses the "slow" dispatch path that checks for interrupts and such.
QUESTION
I'm trying to come up with a simple way to write a class with a constructor that takes a plain object argument, and initialises the instance properties accordingly.
...ANSWER
Answered 2021-Dec-30 at 03:43The compiler cannot perform the analysis on Object.assign(this, init)
to know that all the properties of this
will be initialized as a result. The typings for Object.assign(target, ...args)
don't mutate the type of the target
parameter at all.
You could use a definite assignment assertion for each and every property, to suppress the error:

...ANSWER
Answered 2021-Dec-26 at 01:56Old x86-64 CPUs don't support lzcnt
, so rustc/llvm won't emit it by default. (They would execute it as bsr
but the behavior is not identical.)
Use -C target-feature=+lzcnt
to enable it. Try.
More generally, you may wish to use -C target-cpu=XXX
to enable all the features of a specific CPU model. Use rustc --print target-cpus
for a list.
In particular, -C target-cpu=native
will generate code for the CPU that rustc itself is running on, e.g. if you will run the code on the same machine where you are compiling it.
