Struct CustomJumpHasher

Source 
pub struct CustomJumpHasher<H: Hasher + Clone> { /* private fields */ }
Expand description

A jump hash instance with a custom hash function.

Implementations§

Source§

impl<H: Hasher + Clone> CustomJumpHasher<H>

Source

pub fn new(hasher: H) -> CustomJumpHasher<H>

Initializes jump hash instance with a custom hash function. If the function is going to be used with untrusted inputs, it is recommended to use a non-deterministic, cryptographic hash function.

Source

pub fn slot<T: Hash>(&self, key: &T, slot_count: u32) -> u32

Returns a slot for the key key, out of slot_count available slots.
