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.

Rust Learning Note: Exception Handling
We can utilize third-party libraries to simplify the code above. For example thiserror (https://github.com/dtolnay/thiserror) provides convenien derive macro for Error trait:
- I can't get my mind around Result, Option, or basically how control flow works in most Rust programs

Ideas for crafting CLI in Rust
thiserror crate makes it easy to do so using macros on CliError enum.

I love building a startup in Rust. I wouldn't pick it again.
Depending on your use case, thiserror and/or anyhow.

Hey Rustaceans! Got a question? Ask here (52/2022)!
What is the benefit of splitting a proc-macro crate into (usually) two crates, proc_macro_crate and proc_macro_crate_impl? Why not just have one crate? Does it offer any benefits to to overall compilation times? An example of this can be seen in the thiserror crate where there's a thiserror and thiserror_impl crate.

Parsing of DeviceId
You might want to use thiserror to generate implementation for Error and Display.

Generics can make your Go code slower
I dont think you realize how ridiculous this comment is. Youre comparing 10 lines of Go, with 200 of Rust:

Is this a good way of handling errors in Rust?
There are crates out there that help you reduce this boiler plate. thiserror is good for creating custom errors and color-eyre or anyhow are good for dynamic errors.

Matching with enums
