Trait bdk_chain::ChainOracle

pub trait ChainOracle {
    type Error: Debug;

    fn is_block_in_chain(
        &self,
        block: BlockId,
        chain_tip: BlockId
    ) -> Result<Option<bool>, Self::Error>;
    fn get_chain_tip(&self) -> Result<BlockId, Self::Error>;
}

Represents a service that tracks the blockchain.

The main method is is_block_in_chain which determines whether a given block of BlockId is an ancestor of the chain_tip.

Required Associated Types

type Error: Debug

Error type.

Required Methods

fn is_block_in_chain(
    &self,
    block: BlockId,
    chain_tip: BlockId
) -> Result<Option<bool>, Self::Error>

Determines whether block of BlockId exists as an ancestor of chain_tip.

If None is returned, it means the implementation cannot determine whether block exists under chain_tip.

fn get_chain_tip(&self) -> Result<BlockId, Self::Error>

Get the best chain’s chain tip.
