fn clone_from(&mut self, source: &Self)

impl Hasher for Blake3

type Hash = RawId

This type is used as a hash type in the library. It is recommended to use fixed size u8 array as a hash type. For example, for sha256 the type would be [u8; 32], representing 32 bytes, which is the size of the sha256 digest. Also, fixed sized arrays of u8 by default satisfy all trait bounds required by this type. Read more

fn hash(data: &[u8]) -> Self::Hash

This associated function takes a slice of bytes and returns a hash of it. Used by concat_and_hash function to build a tree from concatenated hashes Read more

fn concat_and_hash(left: &Self::Hash, right: Option<&Self::Hash>) -> Self::Hash

Used by MerkleTree and PartialTree when calculating the root. The provided default implementation propagates the left node if it doesn’t have a sibling. The left node should always be present. The right node is optional. Read more

fn hash_size() -> usize

Returns the byte size of Self::Hash. Default implementation returns mem::size_of::<Self::Hash>(). Usually doesn’t need to be overridden. Used internally by MerkleProof to parse hashes from a serialized proof. Read more
