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).

Understanding Dependencies in Programming
Dependency Management in Other Languages: We've discussed Python and Node.js in this article, but dependency management is a universal concept in programming. Exploring how you handle dependencies in other languages like Java, C#, or Rust could be beneficial. (I think Rust's cargo is an excellent example of a package manager.)

Scriptisto: "Shebang interpreter" that enables writing scripts in compiled langs
Nice hack! Would it have been possible back then to use cargo to pull in some dependencies?
The clean solution of cargo script is here: https://github.com/rust-lang/cargo/issues/12207

Making Rust binaries smaller by default
Yes, I am sure this is going to be a part of Rust 1.77.0 and it will release on 21st March. I say that because of the tag in the PR (https://github.com/rust-lang/cargo/pull/13257#event-11505613...).
I'm no expert on Rust compiler development, but my understanding is that all code that is merged into master is available on nightly. If they're not behind a feature flag (this one isn't), they'll be available in a full release within 12 weeks of being merged. Larger features that need a lot more testing remain behind feature flags. Once they are merged into master, they remain on nightly until they're sufficiently tested. The multi-threaded frontend (https://blog.rust-lang.org/2023/11/09/parallel-rustc.html) is an example of such a feature. It'll remain nightly only for several months.
Again, I'm not an expert. This is based on what I've observed of Rust development.

You can't do that because I hate you
The author provides very surface-level criticism of two Rust tools, but they don't look into why those choices were made.
With about five minutes of my time, I found out:
wrap_comments was introduced in 2019 [0]. There are bugs in the implementation (it breaks Markdown tables), so the option hasn't been marked as stable. Progress on the issue has been spotty.
--no-merge-sources is not trivial to re-implement [1]. The author has already explained why the flag no longer works -- Cargo integrated the command, but not all of the flags. This commit [2] explains why this functionality was removed in the first place.
Rust is open source, so the author of this blog post could improve the state of the software they care about by championing these issues. The --no-merge-sources error message even encourages you to open an issue, presumably so that the authors of Cargo can gauge the importance of certain flags/features.
You could even do something much simpler, like adding a comment to the related issues mentioning that you ran into these rough edges and that it made your life a little worse, or with a workaround that you found.
Alternatively, you can continue to write about how much free software sucks.

Cargo has never frustrated me like npm or pip has. Does Cargo ever get frustrating? Does anyone ever find themselves in dependency hell?
You try to use it as a part of multi-language project, with an external build tool to tie it all together, and you discover that --out-dir flag is still not stabilized over some future compatibility concerns.

Learning Rust by Building a CLI App
To create a new application we'll use cargo (a build tool and also a package manager for Rust. It is used for scaffolding new library/binary projects). So in your projects folder, you can run this command in your terminal:

Leaving Haskell Behind
> ...but at the end of the day Cargo is the reason that Rust is popular.
FWIW, maybe that's true for you, but there are numerous other advantages to the language for which many people choose to use Rust--some even "despite" Cargo: you see Google having had to put in way way WAY too much work to get Bazel working for Rust :/--that it honestly feels a bit like belittling an extremely important language to make this claim so flippantly.
> You can set a default build target for a Cargo project with two lines of configuration, no nightly features necessary...
This doesn't work as, as soon as you start setting target-specific options, it infects the host build, as they incorrectly modelled the problem as some kind of map from targets to flags. If you don't believe me, on your Linux computer, try cross-compile something complicated that will runs on a "least common denominator" Linux distribution, such as CentOS 7.
> Can you clarify what this is referring to?
Sure. I've Googled rust cargo target host bugs for you (which, FWIW, finds a number of bugs I've filed or have talked about, but it isn't as if I have a list anywhere). Note that one of these bugs is "closed", but I still provide them for context as a patch might have been merged but (as you'll find out if you read through all of these) it isn't stable.
https://github.com/rust-lang/cargo/issues/8147
https://github.com/rust-lang/cargo/issues/3349
https://github.com/rust-lang/cargo/pull/9322
https://github.com/rust-lang/cargo/issues/9453
https://github.com/rust-lang/cargo/pull/9753
The result of this work being left incomplete is that increasingly large numbers of "serious" projects--things I'd expect people in packaging land to have heard of, such as BuildRoot--are being forced to set the ridiculous environment variable __CARGO_TEST_CHANNEL_OVERRIDE_DO_NOT_USE_THIS="nightly" in order to get access to a flag that makes Cargo sort of work.
(And yet, I often see people surprised at how long it is taking for various of the more important clients to fully get into using Rust, as the safety issues are so severe from continuing to use C/C++: as you made the contention that you believe the reason why people use Rust is Cargo, I will say the opposite: the reason why we don't see more Rust is also Cargo.)

Rust vs. Go in 2023
What has worked for me so far:
https://doc.rust-lang.org/book/
(do the exercises!)
plus a little bit of:
https://doc.rust-lang.org/cargo/
and
https://doc.rust-lang.org/std/index.html
(There's no need to remember the last URL -- just google "rust xxx" and you will get the right page.)
I'm looking forward to reading this:
