Struct XxHash3_64 

pub struct XxHash3_64 { /* private fields */ }

Calculates the 64-bit hash.

Implementations

impl Hasher

pub fn oneshot(input: &[u8]) -> u64

Hash all data at once. If you can use this function, you may see noticable speed gains for certain types of input.

pub fn oneshot_with_seed(seed: u64, input: &[u8]) -> u64

Hash all data at once using the provided seed and a secret derived from the seed. If you can use this function, you may see noticable speed gains for certain types of input.

pub fn oneshot_with_secret( secret: &[u8], input: &[u8], ) -> Result<u64, OneshotWithSecretError>

Hash all data at once using the provided secret and the default seed. If you can use this function, you may see noticable speed gains for certain types of input.

pub fn oneshot_with_seed_and_secret( seed: u64, secret: &[u8], input: &[u8], ) -> Result<u64, OneshotWithSecretError>

Hash all data at once using the provided seed and secret. If you can use this function, you may see noticable speed gains for certain types of input.

impl Hasher

pub fn new() -> Hasher

Constructs the hasher using the default seed and secret values.

pub fn with_seed(seed: u64) -> Hasher

Constructs the hasher using the provided seed and a secret derived from the seed.

pub fn with_seed_and_secret( seed: u64, secret: impl Into<Box<[u8]>>, ) -> Result<Hasher, SecretTooShortError<Box<[u8]>>>

Constructs the hasher using the provided seed and secret.

pub fn into_secret(self) -> Box<[u8]>

Returns the secret.
