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.

Good example of high performance Rust project without unsafe code?
I'd like the mention my own refactoring of fast-float-rust to remove nearly all unsafe code for merging into Rust core library which left the performance identical to the previous implementation.

Making Rust Float Parsing Fast: libcore Edition
JSON is an interesting example, since the syntax of valid floats is slightly different than what Rust expects. Luckily, I'm the author of a minimal, and am also the author of a PR to bring this to fast-float-rust.
