Struct perfect_hash::PerfectHasher8

pub struct PerfectHasher8<C, H> { /* fields omitted */ }

Methods

impl<C> PerfectHasher8<C, DefaultHasher>

pub fn new() -> Self

If you are not worried about DDoS you should use a faster hasher. Rust defaults to SipHash which is more DDoS resistant, but very slow. I recommend the fasthash crate for a collection of faster hashing algorithms. You should use with_hasher(hasher) or default() when you don't need DDoS resistance.

impl<C, H> PerfectHasher8<C, H> where
    H: Hasher,
    C: Hash + Ord, 

pub fn with_hasher(hasher: H) -> Self

pub fn with_capacity(capacity: u8) -> PerfectHasher8<C, DefaultHasher>

pub fn with_capacity_and_hasher(capacity: u8, hasher: H) -> Self

pub fn unique_id(&mut self, content: C) -> Id<u8>

pub fn get(&self, id: u8) -> Option<&C>
