Struct twox_hash::XxHash32

source · [−]

pub struct XxHash32 { /* private fields */ }

Expand description

Calculates the 32-bit hash. Care should be taken when using this hash.

Although this struct implements Hasher, it only calculates a 32-bit number, leaving the upper bits as 0. This means it is unlikely to be correct to use this in places like a HashMap.

Implementations

source

impl XxHash32

source

pub fn with_seed(seed: u32) -> XxHash32

Constructs the hash with an initial seed

source

pub fn seed(&self) -> u32

source

pub fn total_len(&self) -> u32
