[−][src]Struct ahash::AHasher
A Hasher
for hashing an arbitrary stream of bytes.
Instances of AHasher represent state that is updated while hashing data.
Each method updates the internal state based on the new data provided. Once
all of the data has been provided, the resulting hash can be obtained by calling
finish()
Clone is also provided in case you wish to calculate hashes for two different items that start with the same data.

impl Default for AHasher
[src]
Provides a default Hasher compile time generated constants for keys. This is typically used in conjunction with BuildHasherDefault to create AHashers in order to hash the keys of the map.
Example
use std::hash::BuildHasherDefault; use ahash::{AHasher, ABuildHasher}; use std::collections::HashMap; let mut map: HashMap<i32, i32, ABuildHasher> = HashMap::default(); map.insert(12, 34);
fn default() -> AHasher
[src]
Constructs a new AHasher with compile time generated constants for keys. This means the keys will be the same from one instance to another, but different from build to the next. So if it is possible for a potential attacker to have access to the compiled binary it would be better to specify keys generated at runtime.
Examples
use ahash::AHasher; use std::hash::Hasher; let mut hasher_1 = AHasher::default(); let mut hasher_2 = AHasher::default(); hasher_1.write_u32(1234); hasher_2.write_u32(1234); assert_eq!(hasher_1.finish(), hasher_2.finish());
