What are some common verbose code patterns in rust and unique ways to reduce the said verbosity?
Take a look at the strum crate. https://crates.io/crates/strum

Published my first Crate today to map Environment Variables to Enums
I would be use something like https://github.com/Peternator7/strum if I need map string to enum and serde is not the option.
-
Two-way alternative to enum_kinds crate?
Looks like proper support for this in strum has been proposed.
-
Best way of associating enums with values?
This crate can generate an iterator for you using a macro https://github.com/Peternator7/strum

Hey Rustaceans! Got a question? Ask here (4/2023)!
The strum crate is also good for removing this kind of boilerplate, and worth checking out!

What are some less popular but well-made crates you'd like others to know about?
strum is among my favorite crates to recommend. Favorites of this crate include EnumProperty and EnumIter

What's everyone working on this week (45/2022)?
I released my first crate that provides a derive macro to easily obtain a name of a current variant in an enum as a string. I did it mostly to learn about procedural macros and the process of releasing a crate. I then found out there is strum which does this and much more. Nonetheless, I learned a lot and I found couple of nice tools like ```cargo-release and git-cliff.

Hey Rustaceans! Got a question? Ask here! (33/2022)!
I used https://crates.io/crates/strum to iterate over the enum variants, otherwise you'd have to hardcode the list of variants and wouldn't gain anything.

Questions about enums
If you chose to go with the "derive a trait" route the strum crate might be what you're looking for. It lets you use derive to add information about variant count, discriminants or even iterators over variants to an enum.

CLI Contexts
I recently came across this question (and associated answer) on the clap repository. The answer given is a good one. But I wanted to expand with my own findings and practices, which spurred the motivation for this post.

Getting Started with CLI tools in Rust using Clap
We can also use tuple-like struct syntax and named-field struct syntax for enum variants within our enum; this is because unlike in other OOP languages, Rust enums are actually sum types. You can read more about how powerful Rust enums are in another article we wrote here. You can have optional arguments by simply wrapping the types in Option, but if you want to add a flag to a command you can use bool, since clap recognises that flags are either there or not there. Let's have a look at what this might look like:

Flow Updater JSON Creator
I began by developing a wrapper for the CurseForge API, which turned out to be a lengthy and challenging process but constituted the bulk of the work. Next, I coded the CLI, which was relatively straightforward. Instead of using the clap crate, a Rust tool for generating CLIs, I opted for the following line of code:
-
netcrab: a networking tool
By this time I had already gotten tired of parsing arguments by myself and had looked for something to help with that. I found a really dang good argument parsing library called clap. What makes it so cool is it's largely declarative for common uses. You simply mark up a struct with attributes, and the parser automatically generates the usage and all the argument parsing code.

I made an alternative --help renderer for clap based applications
Is this just referring to wrapping based on the terminal width? That is supported with the wrap_help feature though I have been considering making it a default feature.

Looking for advice around project direction using artix-web
CLI, use Clap. If you want to get fancy, use Tui.

Build a HTTP server with Rust and tokio - Part 1: serving static files
As our CLI is getting more complex, we'll use the clap crate to parse the command line arguments.
