Tuple Fields

0: Fp

Implementations

impl SequenceEventsHash

pub fn empty() -> SequenceEventsHash

The hash representing an empty list of sequence events. Equivalent to Hash::empty_sequence_events wrapped by SequenceEventsHash.

pub fn push_sequence_event_hash(
    sequence_event_hash: Hash,
    sequence_events_hash: SequenceEventsHash
) -> SequenceEventsHash

The hash formed by hash-consing sequence_event_hash with sequence_events_hash.

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

let mut hash_input = HashInput::empty();
HashInput::add_field(&mut hash_input, sequence_event_hash);
HashInput::add_field(&mut hash_input, sequence_events_hash.0);

SequenceEventsHash(Hash::compute_hash(
    HashPrefixState::sequence_events_list(),
    hash_input,
))

pub fn push_sequence_event(
    sequence_event: &SequenceEvent<'_>,
    sequence_events_hash: SequenceEventsHash
) -> SequenceEventsHash

The hash formed by hash-consing sequence_event’s hash with sequence_events_hash.

Equivalent to calling SequenceEventsHash::push_sequence_event on the result of SequenceEvent::hash:

SequenceEventsHash::push_sequence_event_hash(
    SequenceEvent::hash(sequence_event),
    sequence_events_hash,
)

pub fn of_sequence_events(
    sequence_events: &SequenceEvents<'_>
) -> SequenceEventsHash

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

let mut sequence_events_hash = SequenceEventsHash::empty();
for sequence_event in sequence_events.iter() {
    sequence_events_hash =
        SequenceEventsHash::push_sequence_event(sequence_event, sequence_events_hash)
}
sequence_events_hash
