Hey all! Read a lot of good things about Rust and I was getting pretty bored and often annoyed with building new FastAPI apps. I'm just getting started, from my research Poem seems to be doing the same thing as FastAPI kinda and I'm using SeaORM for the DB.

So far I'm loving it, Cargo.toml looks a lot like Poetry in Python but in VSCode it magically shows me the latest versions of all dependencies. Debugging is really nice because I can just copy & paste compiler messages into an LLM or Google them. It was a bit of a hassle to get all dependencies to work together and to get the thing to compile at first but now it works and I'm happy.

That being said is there anything else I need to know? I still have a very limited understanding of the whole ownership thing but e.g. I understand the benefits of passing variables instead of copying them so I guess that's a start?

This mod is written in an unconventional way: it is written in Rust. The Rust code is here. It uses JNI and JVMTI to interact with Java objects. The only Java code in this mod is for loading the compiled native binary into memory.

I'm happy to have received reviews and merged more than 10 patches to GCC lately (12, to be exact). There are around 6 left to merge (and a couple of others to send to the mailing list).

I want to allow the users of my project be able to write the driving logic, while I provide the tools. What are some embedded scripting languages in Rust that can be sandboxed and are easy for absolute beginners?

edit: Thanks for all of your answers, I decided to go with lua using mlua

In order to share the running transaction into a DAO style data management class, I have wrapped the transaction in an Arc and pass it into the DAO.

The issue is, once the transaction is in there I cannot call commit() on it because it cannot be moved out of the Arc anymore, as the commit requires a mut self.

Any ideas on how to work around this?

It might be lack of sleep, but I can't figure this out.

I have a Label, and I want its text to be red when it represents an error, and I want it be green when it represent "good to go".

I found search result for C and maybe a solution for Python, but nothing for Rust.

I tried manually setting the css-classes property and running queue_draw(); it didn't work.

I can have a gtk::Box or a Frame that I place where the Label should go, then declare two Labels, and use set_child() to switch between them, but that seems like an ugly solution.

Do you have a solution?

SOLVED:

I have to add a "." before declaring a CSS "thing" for it to be considered a class.

Ex:

.overlay {
        background: rgba(60, 60, 60, 1);
        font-size: 25px;
}

instead of:

overlay {
        background: rgba(60, 60, 60, 1);
        font-size: 25px;)
}

Just use label.add_css_class(), label.remove_css_class() or label.set_css_classes() and make sure to properly load your CSS style sheets,

After almost 3 years of work, I've finally managed to get this project stable enough to release an alpha version!

I'm proud to present Managarr - A TUI and CLI for managing your Servarr instances! At the moment, the alpha version only supports Radarr.

Not all features are implemented for the alpha version, like managing quality profiles or quality definitions, etc.

Here's some screenshots of the TUI:

Additionally, you can use it as a CLI for Radarr; For example, to search for a new film:

managarr radarr search-new-movie --query "star wars"

Or you can add a new movie by its TMDB ID:

managarr radarr add movie --tmdb-id 1895 --root-folder-path /nfs/movies --quality-profile-id 1

All features available in the TUI are also available via the CLI.

I would like to share a bash script I made for when you want to simply run a rust script once and delete it. Instead of having compile the script with rustc, running the binary and then deleting the binary, you can achive all of this with this bash script below.

The first argument will be the rust script file name. The .rs file extension is optional. The rest of the arguments are passed into the executed binary.

Simply name the bash script to something like rust-run.sh.

#!/bin/bash

#Get file path from first parameter
path=$(dirname "$1")

#Get file name from first parameter
fileName=$(basename "$1")
fileName="${fileName%'.rs'}"

#Compile executable and save it in the same directory as the rust script
rustc "${path}/${fileName}.rs" -o "${path}/${fileName}"

#If rustc commands retuned any errors, unable to compile the rust script
if [ $? -ne 0 ]; then
    return
fi

#Execute compilled executable and pass the rest of the parameters into the executable
"${path}/${fileName}" ${*:2}

#Delete compillled executable
rm "${path}/${fileName}"

If someone wants to rewrite this in rust or add these features into the rustc, feel free to do so.

Hi all,

I'm going through and giving a bunch if different GUI frameworks a go and have tried iced, egui and Slint. Iced was by far the easiest to get started and just seemed fairly logical for layouts, Slint was pretty cool - VSCode actually has like a wysiwyg-editor that allows you to drag components around etc.

Unfortunately I'm having issues getting breakpoints to work when using VSCode, Tauri, plus a Rust frontend (yew, dioxus, etc). I think its because what is compiled isn't where my actual code exists? If I use a JavaScript frontend it hits breakpoints fine, but that's not what I'm wanting to use at the moment.
