Release Notes

rust-lang/rustc-hash (rustc-hash)

v2.0.0

Compare Source

• Replace hash with faster and better finalized hash.
  This replaces the previous "fxhash" algorithm originating in Firefox
  with a custom hasher designed and implemented by Orson Peters (@orlp).
  It was measured to have slightly better performance for rustc, has better theoretical properties
  and also includes a significantly better string hasher.
• Fix no_std builds

v1.2.0

Note: This version has been yanked due to issues with the no_std feature!

• Add a FxBuildHasher unit struct
• Improve documentation
• Add seed API for supplying custom seeds other than 0
• Add FxRandomState based on rand (behind the rand feature) for random seeds
• Make many functions const fn
• Implement Clone for FxHasher struct
