Struct FixedState

pub struct FixedState { /* private fields */ }

A BuildHasher for fast::FoldHashers that all have the same fixed seed.

Not recommended unless you absolutely need determinism.

Implementations

impl FixedState

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

Creates a FixedState with the given seed.
