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.

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

Why Rust?
There is ? as well as the anyhow(https://github.com/dtolnay/anyhow) crate that deals with long nested result chains.
- Anyhow/src/ensure.rs: Rust macro with 675 lines

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.

Looking for general advice on toy project
Give anyhow a look.

Oops, I Did It Again...I Made A Rust Web API And It Was Not That Difficult
I've brought anyhow::Result into scope, making error handling super easy to use. We don't need to specify all our Error types. It can automatically convert any errors that implement std::error::Error, which should be all of them. If an error propagates all the way up to main(), we'll get all the info it's captured printed to stdout.

Idiomatic way to return/break if Err/None
Alternatively, if you've got a lot of error types and you're outside a library (so directly in a binary where you don't plan to reuse code elsewhere) you can use anyhow. This gives you an error type you can basically propagate any other error through. On top of that you can attach context information at every return. It's basically a more complicated Result>.
-
Using workspace for modularization is kind of painful?
One approach is to define a separate error type for each crate and then use anyhow, eyre or Box to wrap the error, whever a function can return errors originating in several different crates.

Can we please stop downvoting people who dislike Rust?
Have you tried anyhow and thiserror for making it as simple as .context("Message") or ? to type-convert and propagate errors up the call stack?

Once we have our string response, we can use the select.rs library to ensure the structure matches our intent. In this case, we are asserting we've received an h1 element with a text body matching the string NOT FOUND!.

Show HN: Voyager – write your own web crawler/scraper as a state machine in rust
Standalone html5ever can be a cumbersome to work with directly, scraper is basically an implementation of the html5ever's `TreeSink` trait, where as `select.rs` uses the hmtl5ever `RcDom` to parse the document but stores it in a more convenient way. If you look for a minimal approach you should at select.rs which basicially only depends on html5ever
