Trait trie_db::Hasher[−][src]

pub trait Hasher: Send + Sync {
    type Out: MaybeDebug + Clone + PartialEq<Self::Out> + Eq + AsRef<[u8]> + AsMut<[u8]> + Default + Send + Copy + Sync + Hash;
    type StdHasher: Default + Send + Sync + Hasher;

    pub const LENGTH: usize;

    pub fn hash(x: &[u8]) -> Self::Out;
}

Trait describing an object that can hash a slice of bytes. Used to abstract other types over the hashing algorithm. Defines a single hash method and an Out associated type with the necessary bounds.

Associated Types

type Out: MaybeDebug + Clone + PartialEq<Self::Out> + Eq + AsRef<[u8]> + AsMut<[u8]> + Default + Send + Copy + Sync + Hash[src]

The output type of the Hasher

type StdHasher: Default + Send + Sync + Hasher[src]

What to use to build HashMaps with this Hasher.
