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.

Crate List - Blessed.rs
https://github.com/google/argh is another minimal library for CLI argument parsing that could be in the list

Rust Web Framework Comparison
My go-to is argh[1], as it's more lightweight while still providing a nice derive-based API.

Immediately off the top of your head what is the best Rust CLI library.
It'll panic if the path contains non-UTF8-able bytes.

fncmd: Command line interface as a function.
Yes clap needs a lot of boilerplate that small programs don't always need, but if you're going to simplify it, I don't think having a bunch of arguments given to the main function is better than having an option struct as in argh. Such an option struct can be given to other functions from the main, can have dedicated consistency check or completion methods, etc.

Newbie frustration: can we KISS more?
Typically programs are configured through a config object. People like to use things like clap, structopt, or argh for passing in arguments through the CLI https://github.com/google/argh. You can also use the env! macro for embedding values in at compile time, or by going through the std::env::var infrastructure for runtime env vars.

Darkroom: A VCR contract testing tool built in Rust
Until the argh crate bumps their version I cannot updater the version on crates.io so the install command currently is: cargo install --git https://github.com/mkatychev/darkroom

Announcement: xflags, fast-to-compile proc macro for cli args
Ahh. The secondary reason I discounted Argh as "unsuitable for purpose" after "Doesn't support using OsString under the hood".

What's the coolest Rust project you've seen that made you go, 'Wow, I didn't know Rust could do that!'?
Hope you are aware that structopt is in maintenance mode and is merged into clap as of v3.

Task manager for Linux using rust
As I understood you need to implement a command line argument parser for that you can use clap https://github.com/clap-rs/clap or structopt https://github.com/TeXitoi/structopt.

I feel like discovering moves like this is a weakness in the ecosystem today. You can check out some of our discussion on raising visibility

clap 3.1: A step towards 4.0
Something I've been giving thought to is how to help structopt users discover that clap3 is their upgrade path. We've put notices in the structopt repo but cargo upgrade and docs.rs won't say anything. See https://github.com/TeXitoi/structopt/issues/525 for more ideas we're considering.

ANN: clap 3.0.0-rc.0!
For myself, I have found serde.rs really useful for undertanding their derives while I've always been frustrated with finding anything in structopt's documentation, so I modeled it more off of serde. This ended up both being in structure and not being in docs.rs. I think it really was the structure that was the frustration point for me but there was interest elsewhere in moving stuff out of docs.rs.

fncmd: Command line interface as a function.
I think it would be nice to have a comparison to clap-derive and/or structopt in the README, as that is what I expect most users would compare this to. The subcommand handling looks especially cumbersome compared to deriving on structs and enums.

Linkerd 2.11 now includes a Kubernetes controller written in Rust
However, the one place I'm a little curious to rewrite things is the CLI... every time we have to deal with cobra I long for Rust's structopt.

vaultssh: A small CLI wrapper for authenticating with SSH keys from Hashicorp Vault
Have you tried https://github.com/TeXitoi/structopt ?

SwayWS - a sway workspace tool which allows easy moving of workspaces to and from outputs
It is written in Rust using the structopt and swayipc crates. It is published on crates.io. The repository is hosted on GitLab. The repository is mirrored on GitHub.
