Hey Rustaceans! Got a question? Ask here! (27/2022)!

• rust-analyzer

  132 13,568 10.0 Rust

  A Rust compiler front-end for IDEs

  

OK, I found the answer. As often happens with Rust, the answer is "no, this is not currently possible." Open GH issue: https://github.com/rust-lang/rust-analyzer/issues/4558

• pmp-library

  2 1,206 9.3 C++

  The Polygon Mesh Processing Library

  

In C++, there is this great mesh processing library called PMP and I have noticed that Rust is lacking in that regard. So I wondered that if I wanted to bring most of the functionality into Rust (and not just use bindings), how would people usually go about this?

• rp-hal

  30 1,261 9.3 Rust

  A Rust Embedded-HAL for the rp series microcontrollers

  

You should join matrix channel on project https://github.com/rp-rs/rp-hal very smart people are figuring this out. From what I understood the firmware is closed sourced and provided as a blob and there is a AT commands API working. So it seems this will be awkward but doable

• Catch

  55 18,020 9.2 C++

  A modern, C++-native, test framework for unit-tests, TDD and BDD - using C++14, C++17 and later (C++11 support is in v2.x branch, and C++03 on the Catch1.x branch)

  

Is there a Catch-like test framework which is tokio aware? I've seen some implementations, but they use #[test] instead of #[tokio::test].

I'm trying to use reqwest to download a file and show it's progress. I found exactly what I need here however this seems to just write ontop of the file rather than resume, That still eludes me. Is there an example somewhere I can look at? Most of the examples I've found here have broken links :/

• exif-rs

  2 179 0.0 Rust

  Exif parsing library written in pure Rust

I dont want the files to waste a lot of space so i decided to resize them. For that i used the resize method from the "image" crate. Everything works fine, until i start to upload images above 5mb. Then the resize method starts to rotate the images. I think i narrowed it down to the resize function deleting any existing exif data inside the image file. That way the orientation flag is removed and the image is in its default position. I already tried to fix this, by saving the exif data before resizing and then rewriting it to the image file. The only library that i could find that supports writing (at least for png and jpeg) was this one: kamadax-exif. The problem is, that when i write the exif data (all the previous data or just the orientation data) the file gets corrupted. Now to my question: Can someone recommend a library that can resize images, that preserves the aspect ratio and does not delete the exif data? if not, does someone have an idea on how to resize the images differently? Or maybe there exists another exif data crate that i can use? I hope this question is understandable, thanks in advance :)

• image

  37 4,517 9.1 Rust

  Encoding and decoding images in Rust (by image-rs)

  

As for image processing, I'd start on crates.io and search for "image processing" and skim through to find the most downloaded crates -- image seems to be the most popular, with over 7 million downloads, so I'd check if that has what you want, and if not photon-rs seemed relatively mature with perhaps more features (albeit far less commonly used)

• rust-bitfield

  1 137 5.4 Rust

  This crate provides macros to generate bitfield-like struct.

The bitfield library has very few examples and I am not sure if it will work...

• reqwest

  57 9,178 8.9 Rust

  An easy and powerful Rust HTTP Client

hyper is kind of a low-level library - if you want to "just make request", then I'd suggest to take a look at https://docs.rs/reqwest :-) (it uses hyper underneath, providing a simpler, high-level interface for it)

• avr-hal

Well then, I'd suggest https://github.com/Rahix/avr-hal :-)
