Struct snapps_txn_reference_impl::sequence_event::SequenceStateHash

pub struct SequenceStateHash(pub Fp);

A hash representing the current sequence state.

Tuple Fields

0: Fp

Implementations

impl SequenceStateHash

pub fn empty() -> SequenceStateHash

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

pub fn push_sequence_events_hash(
    sequence_events_hash: SequenceEventsHash,
    sequence_state_hash: SequenceStateHash
) -> SequenceStateHash

The hash formed by hash-consing sequence_events_hash with sequence_state_hash.

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

let mut hash_input = HashInput::empty();
HashInput::add_field(&mut hash_input, sequence_events_hash.0);
HashInput::add_field(&mut hash_input, sequence_state_hash.0);
SequenceStateHash(Hash::compute_hash(
    HashPrefixState::sequence_state(),
    hash_input,
))

pub fn push_sequence_events(
    sequence_events: &SequenceEvents<'_>,
    sequence_state_hash: SequenceStateHash
) -> SequenceStateHash

The hash formed by hash-consing sequence_events’s hash with sequence_state_hash.

Equivalent to calling SequenceStateHash::push_sequence_events on the result of SequenceEventsHash::of_sequence_events:

SequenceStateHash::push_sequence_events_hash(
    SequenceEvents::hash(sequence_events),
    sequence_state_hash,
)
