The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Making Rust Float Parsing Fast: libcore Edition
So, what about safety? fast-float-rust uses unsafe code fairly liberally, so how do the merged changes fix that? Well, all unsafe code except when needed was removed, and it was shown to have no impact on performance or even assembly generation. In fact, the generated assembly is slightly better in some cases. Every call to an unsafe function can be trivially shown to be correct, and all but 1 call has the following format:

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.

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.
