Rust

You ever write a @rust game where the player walks into a dungeon, gets punched in the face by a goblin, drinks a healing potion like it’s chamomile, and keeps going like nothing happened?

Because I just did.

Structs, enums, and reckless bravery: the perfect tea blend.

Maybe the question is not well written, but it's because I do not really know what's happening in here. I'm learning Rust, I'm doing pretty good, but this is the second time that stomp with this.

First, I thought that only the Add trait would be enough, but the LSP keep saying me this if I do not add the "restriction", as far as I know.

What I do not get is what <Output = T> is. I know that is using the type T, but why it is assigned to Output?

The first time that I saw something similar was in the Rust book that comes with rustup, just look at the next function signature

Thank you for you help, you are awesome.

We've got a few bugs fixed that allowed us to fully bootstrap the Rust compiler with rustc_codegen_gcc and to fix the CI for Rust for Linux compiled with rustc_codegen_gcc. We hope to improve our testing within the Rust repo in order to allow us to move faster towards our goals.

Ideal for stress relief when fighting the borrow checker!

Hi everyone!

I'm conducting a brief survey (takes less than 1 minute) to better understand the Rust open source community. I'm particularly interested in learning about who contributes to Rust projects and what motivates or prevents people from getting involved.

I hope insights from this survey will help us identify better ways to support and engage potential contributors in the Rust community.

Thanks for taking the time to share your perspective!

I just learned the basics of macros and figured I'd give a shot trying to solve a problem I've had for a while. Theres just one derive trait in this crate, Variants, that when derived will generate a constant array that holds all of the enum's variants along with a method that exposes a static reference to the constant array.

Give it a look, leave some feedback, maybe even open up a PR. I hope you like what you see!

Hi all,

I don't know where would be the best place to post this, but I wanted some people's feedback on a DSL that I wrote for network analysis.

I am using nom for writing the lexer and parser, then using abi_stable crate for data types so that you can write plugins to the language and load them dynamically as well.

This language is made to work by loading a tree graph (network) and then call a bunch of node or network functions that work on it. There are different ways you can run functions, and use node/network attributes.

I am mostly self-taught, so it took a lot of years to get to a level where I could write something like this. I am learning a lot and having a lot of fun in the process, but I want this to develop into something that can have a practical usefulness to people. Since I am in the field of hydrology, I am making it with river networks in the mind.

To try it out, you can either download the executables for windows from the releases page, or you can compile it using cargo (for all OS; except android where GUI won't work, CLI will work in termux). I have some basic examples in the Learn By Examples section of the User Guide that you can follow.

• The repo is at: https://github.com/Nadi-System/nadi-system
• And the User Guide is at: https://nadi-system.github.io/ (although the guide also talks about other parts of the system, you can ignore them for this post)

Please let me know if you can't compile/use it as well. I have tried to make sure it has required instructions, but I could have missed something.
