Making Rust Float Parsing Fast: libcore Edition
If you're interested, I've basically compiled a list of all the different float formats from over 50 programming and data interchange formats.

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.

I've already done that (just pushed it - here).
