Implementations

impl<L: ChainListener + Ord> ChainTracker<L>

pub fn new(
    network: Network,
    height: u32,
    tip: BlockHeader
) -> Result<Self, Error>

Create a new tracker

pub fn tip(&self) -> BlockHeader

Current chain tip header

pub fn headers(&self) -> &VecDeque<BlockHeader>

Headers past the tip

pub fn height(&self) -> u32

Height of current chain tip

pub fn remove_block(
    &mut self,
    txs: Vec<Transaction>,
    txs_proof: Option<PartialMerkleTree>
) -> Result<BlockHeader, Error>

Remove block at tip due to reorg

pub fn add_block(
    &mut self,
    header: BlockHeader,
    txs: Vec<Transaction>,
    txs_proof: Option<PartialMerkleTree>
) -> Result<(), Error>

Add a block, which becomes the new tip

pub fn add_listener(&mut self, listener: L, initial_txid_watches: Set<Txid>)

Add a listener and initialize the watched outpoint set

pub fn add_listener_watches(&mut self, listener: L, watches: Set<OutPoint>)

Add more watches to a listener
