Tuple Fields

0: Fp

Implementations

impl EventsHash

pub fn empty() -> EventsHash

The hash representing an empty list of events. Equivalent to Hash::empty_events wrapped by EventsHash.

pub fn push_event_hash(event_hash: Hash, events_hash: EventsHash) -> EventsHash

The hash formed by hash-consing event_hash with events_hash.

Creates a HashInput formed by adding the events_hash and events_hash field elements in order, then computing the resulting hash with HashPrefixState::events_list.

let mut hash_input = HashInput::empty();
HashInput::add_field(&mut hash_input, event_hash);
HashInput::add_field(&mut hash_input, events_hash.0);

EventsHash(Hash::compute_hash(
    HashPrefixState::events_list(),
    hash_input,
))

pub fn push_event(event: &Event<'_>, events_hash: EventsHash) -> EventsHash

The hash formed by hash-consing event’s hash with events_hash.

Equivalent to calling EventsHash::push_event on the result of Event::hash:

EventsHash::push_event_hash(Event::hash(event), events_hash)

pub fn of_events(events: &Events<'_>) -> EventsHash

Compute the hash of events by starting with empty and calling push_event on each event in turn.

let mut events_hash = EventsHash::empty();
for event in events.iter() {
    events_hash =
        EventsHash::push_event(event, events_hash)
}
