Struct SecureMultisetHash

pub struct SecureMultisetHash { /* private fields */ }

The SecureMultisetHash structure maintains a running elliptic curve hash.

Implementations

impl SecureMultisetHash

pub fn new() -> Self

Creates a new, empty multiset hash (the identity element).

pub fn add(&mut self, element: &[u8])

Add an element to the multiset hash.

pub fn remove(&mut self, element: &[u8])

Removes an element (provided as a byte slice) from the multiset hash.

This is done by adding the inverse (negation) of H(element).

pub fn add_elements<'a, T>(&mut self, elements: &'a [T])

where T: AsRef<[u8]> + Sync,

Adds multiple elements in parallel.

pub fn remove_elements<'a, T>(&mut self, elements: &'a [T])

where T: AsRef<[u8]> + Sync,

Removes multiple elements in parallel.

pub fn get_compressed(&self) -> Option<[u8; 33]>

pub fn get_digest(&self) -> Option<[u8; 32]>
