Details
Package fast-float
Version 0.2.0
Warning unsound
URL aldanor/fast-float-rust#35
Patched Versions n/a

fast-float contains multiple soundness issues:

  1. Undefined behavior when checking input length, which has been merged but no package pubished.
  2. Many functions marked as safe with non-local safety guarantees

The library is also unmaintained.

Alternatives

For quickly parsing floating-point numbers third-party crates are generally no longer needed. A fast float parsing algorithm by the author of lexical has been merged into libcore. When requiring direct parsing from bytes and/or partial parsers, the fast-float2 fork of fast-float containing these security patches and reduces overall usage of unsafe.
