Struct Standard 

pub struct Standard<H: CHasher> { /* private fields */ }

The standard hasher to use with an MMR for computing leaf, node and root digests. Leverages no external data.

Implementations

impl<H: CHasher> Standard<H>

pub fn new() -> Self

Creates a new Standard hasher.

Trait Implementations

impl<H: CHasher> Default for Standard<H>

fn default() -> Self

Returns the “default value” for a type.

impl<H: CHasher> Hasher<H> for Standard<H>

fn inner(&mut self) -> &mut H

Access the inner CHasher hasher.

fn fork(&self) -> impl Hasher<H>

Fork the hasher to provide equivalent functionality in another thread. This is different than Clone::clone because the forked hasher need not be a deep copy, and may share non-mutable state with the hasher from which it was forked.

fn leaf_digest(&mut self, pos: u64, element: &[u8]) -> H::Digest

Computes the digest for a leaf given its position and the element it represents.

fn node_digest( &mut self, pos: u64, left: &H::Digest, right: &H::Digest, ) -> H::Digest

Computes the digest for a node given its position and the digests of its children.

fn root<'a>( &mut self, size: u64, peak_digests: impl Iterator<Item = &'a H::Digest>, ) -> H::Digest

Computes the root for an MMR given its size and an iterator over the digests of its peaks in decreasing order of height.

fn digest(&mut self, data: &[u8]) -> H::Digest

Compute the digest of a byte slice.
