Implementations
impl RandomState
impl RandomState
pub fn new() -> RandomState
pub fn new() -> RandomState
Use randomly generated keys
pub fn generate_with(k0: u64, k1: u64, k2: u64, k3: u64) -> RandomState
pub fn generate_with(k0: u64, k1: u64, k2: u64, k3: u64) -> RandomState
Allows for supplying seeds, but each time it is called the resulting state will be different. This is done using a static counter, so it can safely be used with a fixed keys.
pub const fn with_seeds(k0: u64, k1: u64, k2: u64, k3: u64) -> RandomState
pub const fn with_seeds(k0: u64, k1: u64, k2: u64, k3: u64) -> RandomState
Allows for explicitly setting the seeds to used.
Trait Implementations
impl BuildHasher for RandomState
impl BuildHasher for RandomState
pub fn build_hasher(&self) -> AHasher
pub fn build_hasher(&self) -> AHasher
Constructs a new AHasher with keys based on this RandomState object. This means that two different RandomStates will will generate AHashers that will return different hashcodes, but Hashers created from the same BuildHasher will generate the same hashes for the same input data.
Examples
use ahash::{AHasher, RandomState}; use std::hash::{Hasher, BuildHasher}; let build_hasher = RandomState::new(); let mut hasher_1 = build_hasher.build_hasher(); let mut hasher_2 = build_hasher.build_hasher(); hasher_1.write_u32(1234); hasher_2.write_u32(1234); assert_eq!(hasher_1.finish(), hasher_2.finish()); let other_build_hasher = RandomState::new(); let mut different_hasher = other_build_hasher.build_hasher(); different_hasher.write_u32(1234); assert_ne!(different_hasher.finish(), hasher_1.finish());
