Struct ckb_types::core::BlockBuilder

pub struct BlockBuilder { /* fields omitted */ }

An advanced builder for BlockView.

Base on packed::BlockBuilder but added lots of syntactic sugar.

Implementations

impl BlockBuilder

pub fn version(self, v: Uint32) -> Self

Sets header.version.

pub fn parent_hash(self, v: Byte32) -> Self

Sets header.parent_hash.

pub fn timestamp(self, v: Uint64) -> Self

Sets header.timestamp.

pub fn number(self, v: Uint64) -> Self

Sets header.number.

pub fn transactions_root(self, v: Byte32) -> Self

Sets header.transactions_root.

pub fn proposals_hash(self, v: Byte32) -> Self

Sets header.proposals_hash.

pub fn compact_target(self, v: Uint32) -> Self

Sets header.compact_target.

pub fn extra_hash(self, v: Byte32) -> Self

Sets header.extra_hash.

pub fn epoch(self, v: Uint64) -> Self

Sets header.epoch.

pub fn dao(self, v: Byte32) -> Self

Sets header.dao.

pub fn nonce(self, v: Uint128) -> Self

Sets header.nonce.

pub fn uncle(self, v: UncleBlockView) -> Self

Pushes an item into uncles.

pub fn uncles<T>(self, v: T) -> Self where
    T: IntoIterator<Item = UncleBlockView>, 

Extends uncles with the contents of an iterator.

pub fn set_uncles(self, v: Vec<UncleBlockView>) -> Self

Sets uncles.

pub fn transaction(self, v: TransactionView) -> Self

Pushes an item into transactions.

pub fn transactions<T>(self, v: T) -> Self where
    T: IntoIterator<Item = TransactionView>, 

Extends transactions with the contents of an iterator.

pub fn set_transactions(self, v: Vec<TransactionView>) -> Self

Sets transactions.

pub fn proposal(self, v: ProposalShortId) -> Self

Pushes an item into proposals.

pub fn proposals<T>(self, v: T) -> Self where
    T: IntoIterator<Item = ProposalShortId>, 

Extends proposals with the contents of an iterator.

pub fn set_proposals(self, v: Vec<ProposalShortId>) -> Self

Sets proposals.

pub fn header(self, header: HeaderView) -> Self

Set header.

pub fn build(self) -> BlockView

Converts into BlockView and recalculates all hashes and merkle roots in the header.

pub fn build_unchecked(self) -> BlockView

Converts into BlockView but does not refresh all hashes and all merkle roots in the header.

Notice

BlockView created by this method could have invalid hashes or invalid merkle roots in the header.
