Struct `SeedableRandomState`

pub struct SeedableRandomState { /* private fields */ }

A BuildHasher for fast::FoldHasher that is randomly initialized by default, but can also be initialized with a specific seed.

This can be useful for e.g. testing, but the downside is that this type has a size of 16 bytes rather than the 8 bytes RandomState is.

Implementations

`impl SeedableRandomState`

fn random() -> Self: Generates a random SeedableRandomState, similar to RandomState.
fn fixed() -> Self: Generates a fixed SeedableRandomState, similar to FixedState.
fn with_seed(per_hasher_seed: u64, shared_seed: &'static SharedSeed) -> Self: Generates a SeedableRandomState with the given per-hasher seed and SharedSeed.
