impl CompactBlock

pub fn calc_header_hash(&self) -> Byte32

impl CompactBlock

pub fn build_from_block(
    block: &BlockView,
    prefilled_transactions_indexes: &HashSet<usize>
) -> Self

Builds a CompactBlock from block and prefilled transactions indexes.

pub fn block_short_ids(&self) -> Vec<Option<ProposalShortId>>

Takes proposal short ids for the transactions which are not prefilled.

pub fn txs_len(&self) -> usize

Calculates the length of transactions.

pub fn short_id_indexes(&self) -> Vec<usize>

Collects the short id indexes.

pub fn extra_field(&self, index: usize) -> Option<Bytes>

Gets the i-th extra field if it exists; i started from 0.

pub fn extension(&self) -> Option<Bytes>

Gets the extension field if it existed.

Panics

Panics if the first extra field exists but not a valid Bytes.
