Struct SharedSeed 

pub struct SharedSeed { /* private fields */ }

A random seed intended to be shared by many different foldhash instances.

This seed is consumed by FoldHasher::with_seed, and SeedableRandomState::with_seed.

Implementations

impl SharedSeed

pub fn global_random() -> &'static SharedSeed

Returns the globally shared randomly initialized SharedSeed as used by RandomState.

pub const fn global_fixed() -> &'static SharedSeed

Returns the globally shared fixed SharedSeed as used by FixedState.

pub const fn from_u64(seed: u64) -> Self

Generates a new SharedSeed from a single 64-bit seed.

Note that this is somewhat expensive so it is suggested to re-use the SharedSeed as much as possible, using the per-hasher seed to differentiate between hash instances.

Trait Implementations

impl Clone for SharedSeed

fn clone(&self) -> SharedSeed

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SharedSeed

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
