Implementations

impl HeaderBuilder<HeaderSetParenting>

pub fn new( version: BlockVersion, contents: &Contents ) -> HeaderBuilder<HeaderSetParenting>

Create a new Header builder starting from the full content.

This doesn’t need the content directly, but only uses the content to calculate the content hash and the content size, and make sure this is consistent

pub fn new_raw( version: BlockVersion, content_hash: &Hash, content_size: u32 ) -> HeaderBuilder<HeaderSetParenting>

recommended to use new(), this is only for test

impl HeaderBuilder<HeaderSetParenting>

pub fn set_genesis(self) -> HeaderBuilder<HeaderSetDate>

Set the header as a genesis header:

• the depth starts at 0
• the parent is set to the “null hash” (hash all 0)

pub fn set_parent( self, parent_hash: &Hash, chain_length: ChainLength ) -> HeaderBuilder<HeaderSetDate>

Set the header as a general block, with a specific depth and parent hash

impl HeaderBuilder<HeaderSetDate>

pub fn set_date(self, date: BlockDate) -> HeaderBuilder<HeaderCommonDone>

Set the date of this block

impl HeaderBuilder<HeaderCommonDone>

pub fn into_unsigned_header(self) -> Option<HeaderUnsigned>

Finalized to an unsigned header

pub fn into_bft_builder( self ) -> Option<HeaderBftBuilder<HeaderSetConsensusData>>

Tentatively transition to a BFT Header builder

pub fn into_genesis_praos_builder( self ) -> Option<HeaderGenesisPraosBuilder<HeaderSetConsensusData>>

Tentatively transition to a Genesis-Praos Header builder
