Struct BlockIndices

Source 
pub struct BlockIndices { /* private fields */ }
Expand description

Internal indices of the blocks and chains.

This is main connection between blocks, chains and canonical chain.

It contains a list of canonical block hashes, forks to child blocks, and a mapping of block hash to chain ID.

Implementations§

Source§

impl BlockIndices

Source

pub fn new( last_finalized_block: BlockNumber, canonical_chain: BTreeMap<BlockNumber, BlockHash>, ) -> Self

Create new block indices structure

Source

pub const fn fork_to_child( &self, ) -> &HashMap<BlockHash, LinkedHashSet<BlockHash>>

Return fork to child indices

Source

pub fn pending_blocks(&self) -> (BlockNumber, Vec<BlockHash>)

Returns all pending block hashes.

Pending blocks are considered blocks that are extending the canonical tip by one block number and have their parent hash set to the canonical tip.

Source

pub const fn last_finalized_block(&self) -> BlockNumber

Last finalized block

Source

pub fn canonicalize_blocks( &mut self, blocks: &BTreeMap<BlockNumber, SealedBlockWithSenders>, )

Remove all blocks from canonical list and insert new blocks to it.

It is assumed that blocks are interconnected and that they connect to canonical chain

Source

pub fn canonical_hash(&self, block_number: &BlockNumber) -> Option<BlockHash>

Returns the block hash of the canonical block with the given number.

Source

pub fn canonical_number(&self, block_hash: &BlockHash) -> Option<BlockNumber>

Returns the block number of the canonical block with the given hash.

Source

pub fn canonical_tip(&self) -> BlockNumHash

get canonical tip
