Struct fxhash::FxHasher

source ·
pub struct FxHasher { /* private fields */ }
Expand description

This hashing algorithm was extracted from the Rustc compiler. This is the same hashing algoirthm used for some internal operations in FireFox. The strength of this algorithm is in hashing 8 bytes at a time on 64-bit platforms, where the FNV algorithm works on one byte at a time.

This hashing algorithm should not be used for cryptographic, or in scenarios where DOS attacks are a concern.
