Multiple soundness issues

Details
Status	unsound
Package	fast-float
Version	0.2.0
URL	aldanor/fast-float-rust#35
Date	2024-10-31

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.

See advisory page for additional details.

This crate should move from fast-float which is abandoned to fast-float2

Close this issue please. boa already uses fast-float2 (in main at least).

[storopoli]

No don't close this issue before tagging a new release.
This is the latest release Cargo.toml:

I believe this can be closed now that v0.20.0 has been released. https://github.com/boa-dev/boa/releases/tag/v0.20
