Struct FixedState 

pub struct FixedState { /* private fields */ }

A BuildHasher for fast::FoldHasher that always has the same fixed seed.

Not recommended unless you absolutely need determinism.

Implementations

impl FixedState

pub const fn with_seed(per_hasher_seed: u64) -> FixedState

Creates a FixedState with the given per-hasher-seed.
