QUESTION
Context
I have a char
variable on which I need to apply a transformation (for example, add an offset). The result of the transformation may or may not overflow.
I don't really care of the actual value of the variable after the transformation is performed.
The only guarantee I want to have is that I must be able to retrieve the original value if I perform the transformation again but in the opposite way (for example, substract the offset).
Basically:
...ANSWER
Answered 2022-Mar-21 at 15:37I know that signed types overflow is undefined behaviour,
True, but does not apply here.
a += 140;
is not signed integer overflow, not UB. That is like a = a + 140;
a + 140
does not overflow when a
is 8-bit signed char
or unsigned char
.
The issue is what happens when the sum a + 140
is out of char
range and assigned to a char
.
Otherwise, the new type is signed and the value cannot be represented in it; either the result is implementation-defined or an implementation-defined signal is raised. C17dr § 6.3.1.3 3
It is implementation defined behavior, when char
is signed and 8-bit - to assign a value outside the char
range.
Usually the implementation defined behavior is a wrap and fully defined so a += 140;
is fine as is.
Alternatively the implementation defined behavior might have been to cap the value to the char
range when char
is signed.

I'm trying to create a Printing Server in rust and face a problem when trying to send JSON as a response.
I've found on the Rocket documentation that is really easy to send JSON as a response: You just have to use the Serde library.
Unfortunatly, that wasn't so simple for me...
Here is my current code :
...ANSWER
Answered 2021-Aug-06 at 14:23You are using rocket 0.5.0-rc.1 and rocket_contrib 0.4.10. While Json
from rocket_contrib does implement Responder
, it implements the Responder
trait of Rocket v4, not that of Rocket v5.
In Rocket v5, Json
is not part of rocket_contib
anymore, but included in the rocket
crate (note that you need to enable the json
feature on the rocket
crate):

QUESTION
Im trying to make a Pyqt5 app with aiohttp request, and asyncio tasks. Im using quamash package too and it requires Python 3.7 so i installed this version.(it didn't work on Python 3.10) The main reason i use asyncio and quamash is because i want to do requests and without freezing the GUI of the app.
I get this error when i click the Start button and close the app:

package:
I fixed the error by installing previous release of aiohttp Orignally i had aiohttp 3.8.1.dist installed. I also knew it was working for me before on other version of aiohttp, so i looked up pypi.org/project/aiohttp/#history and turn out i had to uninstall aiohttp and install aiohttp==3.7.4.

QUESTION
I'm currently working on a web app that can connect to Phantom Wallet. I've established the connection and have successfully retrieved the wallet's public key. The problem is, I can't seem to find any solution to get the account balance.
For reference, I wanted to display the account balance just like how solanart.io displays it.
Note that I've gone through all related docs (Solana/web3.js, Solana JSON RPC API etc). Please guide me as I'm still new to JSON RPC API.
For a heads up, I'm using vanilla js.
...ANSWER
Answered 2021-Oct-13 at 22:14The RPC method that you're using does not exist. You'll want to use getBalance
to get the SOL on the wallet: https://docs.solana.com/developing/clients/jsonrpc-api#getbalance
To get all of the non-SOL token balances owned by that wallet, you'll have to use getTokenAccountsByOwner
using that wallet id: https://docs.solana.com/developing/clients/jsonrpc-api#gettokenaccountsbyowner
QUESTION
I am streaming the download of an S3 file using amazonka, and I use the sinkBody
function to continue with the streaming. Currently, I download the file as follows:
ANSWER
Answered 2021-Oct-27 at 18:04Well, the purpose of a streaming library like conduit
is to realize some of the benefits of lazy data structures and actions (lazy ByteString
s, lazy I/O, etc.) while better controlling memory usage. The purpose of the sinkLazy
function is to take data out of the conduit
ecosystem with its well controlled memory footprint and back into the wild West of lazy objects with associated space leaks. So, that's your problem right there.
Rather than sink the stream out of conduit
and into a lazy ByteString
, you probably want to keep the data in conduit
and sink the stream directly into the file, using something like sinkFile
. I don't have an AWS test program up and running, but the following type checks and probably does what you want:
