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:
