Implementations
impl RandomState
[src]
impl RandomState
[src]pub fn new() -> RandomState
[src]
pub fn new() -> RandomState
[src]Use randomly generated keys
pub fn generate_with(k0: u64, k1: u64, k2: u64, k3: u64) -> RandomState
[src]
pub fn generate_with(k0: u64, k1: u64, k2: u64, k3: u64) -> RandomState
[src]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
[src]
pub const fn with_seeds(k0: u64, k1: u64, k2: u64, k3: u64) -> RandomState
[src]Allows for explicitly setting the seeds to used.
Trait Implementations
impl BuildHasher for RandomState
[src]
impl BuildHasher for RandomState
[src]fn build_hasher(&self) -> AHasher
[src]
fn build_hasher(&self) -> AHasher
[src]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());
