Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to package a Rust app using Nix
I'll use nixpkgs' buildRustPackage. There's a few other tools, my favorite being crate2nix, but we'll leave that to a future tutorial.
-
Nix shell related questions (for rust)
If you want to iterate with nix instead of cargo, crate2nix and cargo2nix provides more caching and more fine control over your dependencies. I haven't used these two so you would have to decide for yourself. You may also want to try out nocargo for something more experimental.

Introducing Crane: Composable and Cacheable Builds with Cargo and Nix
I'm yet to try it out, but from the blog post, the README and the source it appears that Crane builds all dependencies in one derivation (separately from the main crate). This means that if a dependency gets added, removed or changed, all dependencies of a crate will be rebuilt. This is in contrast with https://github.com/kolloch/crate2nix, which does build every dependency in a separate package, thus you don't need to rebuild other dependencies if you only change a small part of the tree.

Nixery – Docker images on the fly with Nix
Yes, you will have to package it if it's not already in nixpkgs.
The good news is once you learn how, it's basically trivial with crate2nix[0], which can autogenerate nix derivations from rust crates

Help with Nix and Rust
From my quick reading of cargo2nix's webpage yes. https://github.com/kolloch/crate2nix has a workspaces section.
-
How do you install packages not in Nixpkgs?
As for your two applications, they're both written in Rust, and I like https://github.com/kolloch/crate2nix as a way to package Rust crates with Nix. BTW, wezterm is already in nixpkgs!
-
Nix-ifying a Rust project
I like the way crate2nix works. I have made a flake template for it here. Sometimes it requires a couple of overrides to fix some misbehaving crates (see https://github.com/balsoft/simple-osd-daemons/blob/master/flake.nix#L29 for an example of such overrides), but otherwise it's fantastic. It doesn't require any hash nonsense, it downloads and builds all the crates separately (unlike naersk or other solutions) so you get all the benefits of Nix (reproducibility and proper caching).

How to do a full, reproducible archive of a Rust project?

Understanding Overlays and direnv nix shell inheritance
I'm trying to understand overlays in order to make a proper rustup install (I've read that this overlay is the best way to go).

Diving straight into flakes with no channels?
real-world example: https://github.com/oxalica/rust-overlay/blob/master/flake.nix

An example providing rust toolchain for Linux/macOS using devenv.sh
In this language context specifically, if one wanted to manage their workspace with Nix I would reach for Riff and/or oxalica/rust-overlay first, since they are deliberately more aware of Rust-specific nuance. In the latter's case it has compatibility paths with rustup-toolchain files as well, for allowing your peers who can't or won't adopt Nix to continue to feel like first-class participants in the project. Another alternative I don't have experience with would be nix-community/fenix.

Introducing Riff, a Nix-based tool for automatically providing external dependencies to Rust projects
p.s. I'm not sure if it's mentioned much of anywhere, but it'd be neat if there was a way to figure out the appropriate cargo from a rust-toolchain/rust-toolchain.toml if present, ala https://github.com/oxalica/rust-overlay. Funnily enough 95% of my development time is in Rust, but I don't actually have it installed globally, fun times being a NixOS user. I'd definitely make the argument that cargo is an external dependency!

Have a few questions about NixOS
Many of us have moved to https://github.com/oxalica/rust-overlay over Mozilla's overlay.
-
Rust Environment and Docker Build with Nix Flakes
We added rust-overlay, so we can easily specify different rust versions without relying on nixpkgs to give us what ever rust version in there.
-
Switching from pyenv, rbenv, goenv and nvm to asdf – yujinyuz
If it's Rust, you can use https://github.com/oxalica/rust-overlay to get any version you want very easily without pinning an instance of nixpkgs just for it.
asdf does not allow you to keep three different versions of the same language, so I'm not sure how that compares? It's not super-trivial to do in Nix, but at least you can do it.
asdf is also no different than Nix when it comes to minor/major versions. You're at the mercy of what the plugin does, other than that you have to create your own plugin from scratch or make a fork. Nix has the option to patch things up more easily at least.

Fenix: rust toolchains for all channels and rust-analyzer nightly
How does this compare to https://github.com/oxalica/rust-overlay/ ? Can fenix ingest a rust-toolchain file and provide packages from it?
Can you say a bit about how this compares to oxalica’s rust overlay?
-
