Struct PartialBlockchainUpdates 

pub struct PartialBlockchainUpdates {
    pub new_peaks: MmrPeaks,
    /* private fields */
}

Contains all the partial blockchain information that needs to be added in the client’s store after a sync: block headers, authentication nodes and the MMR peaks at the new sync height.

Insert-only: entries are staged once known to be worth keeping, never revised or removed.

Fields

new_peaks: MmrPeaks

MMR peaks at the new sync height.

Implementations

impl PartialBlockchainUpdates

pub fn insert(&mut self, block_header: BlockHeader, is_relevant: bool)

Adds a block header to this PartialBlockchainUpdates.

On a repeated block number the is_relevant flag is OR-ed — the chain tip block may itself be relevant — so it only ever moves from false to true, matching Store::insert_block_header’s one-way upgrade.

pub fn extend_authentication_nodes( &mut self, nodes: impl IntoIterator<Item = (InOrderIndex, Word)>, )

Stages authentication nodes for storage.

Kept as one flat set rather than per-header, since tracked blocks’ paths share internal nodes.

pub fn block_headers(&self) -> impl Iterator<Item = &(BlockHeader, bool)>

Returns the new block headers to be stored, along with a flag indicating whether each block is relevant and should remain tracked.

pub fn block_headers_to_store( &self, sync_height: BlockNumber, ) -> impl Iterator<Item = &(BlockHeader, bool)>

Returns block headers that need to be persisted for this update.

pub fn new_authentication_nodes(&self) -> &[(InOrderIndex, Word)]

Returns the new authentication nodes that are meant to be stored in order to authenticate block headers.
