Struct highway::HighwayBuilder

pub struct HighwayBuilder(_);

Main HighwayHash implementation that delegates to one of the other implementations depending on the target compiled for and a runtime CPU check.

In order of preference:

• AvxHash
• SseHash
• PortableHash

Methods

impl HighwayBuilder

pub fn new(key: &Key) -> Self

Creates a new hasher based on compilation and runtime capabilities

Trait Implementations

impl Debug for HighwayBuilder

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

Formats the value using the given formatter.

impl HighwayHash for HighwayBuilder

fn hash64(self, data: &[u8]) -> u64

Convenience function for hashing all data in a single call and receiving a 64bit hash. Results are equivalent to appending the data manually.

fn hash128(self, data: &[u8]) -> u128

Convenience function for hashing all data in a single call and receiving a 128bit hash. Results are equivalent to appending the data manually.

fn hash256(self, data: &[u8]) -> (u128, u128)

Convenience function for hashing all data in a single call and receiving a 256bit hash. Results are equivalent to appending the data manually.

fn append(&mut self, data: &[u8])

Adds data to be hashed. If it is important, the performance characteristics of this function differs depending on the amount of data previously hashed and the amount of data to be hashed. For instance, if one appends 50, 1 byte slices then appending the 32nd byte will have a performance outlier as the internal 32 byte block is complete and internally processed.

fn finalize64(self) -> u64

Consumes the hasher to return the 64bit hash

fn finalize128(self) -> u128

Consumes the hasher to return the 128bit hash

fn finalize256(self) -> (u128, u128)

Consumes the hasher to return the 256bit hash
