FoldHasher

reth_revm::primitives::map::foldhash::quality

Struct FoldHasher 

pub struct FoldHasher { /* private fields */ }
Expand description

A Hasher instance implementing foldhash, optimized for quality.

While you can create one directly with FoldHasher::with_seed, you most likely want to use RandomState, SeedableRandomState or FixedState to create FoldHashers.
