Struct FbBuildHasher

pub struct FbBuildHasher<const N: usize> { /* private fields */ }

BuildHasher optimized for hashing fixed-size byte arrays.

Works best with fxhash, enabled by default with the “map-fxhash” feature.

NOTE: this hasher accepts only N-length byte arrays! It is invalid to hash anything else.
