Struct BlockVerifierRouter 

Source 
struct BlockVerifierRouter<S, V>
where
    S: Service<Request, Response = Response, Error = BoxError> + Send + Clone + 'static,
    S::Future: Send + 'static,
    V: Service<Request, Response = Response, Error = BoxError> + Send + Clone + 'static,
    V::Future: Send + 'static,
{
    checkpoint: CheckpointVerifier<S>,
    max_checkpoint_height: Height,
    block: SemanticBlockVerifier<S, V>,
}
Expand description

The block verifier router routes requests to either the checkpoint verifier or the semantic block verifier, depending on the maximum checkpoint height.

§Correctness

Block verification requests should be wrapped in a timeout, so that out-of-order and invalid requests do not hang indefinitely. See the router module documentation for details.

Fields§

§checkpoint: CheckpointVerifier<S>

The checkpointing block verifier.

Always used for blocks before Canopy, optionally used for the entire checkpoint list.

§max_checkpoint_height: Height

The highest permitted checkpoint block.

This height must be in the checkpoint verifier’s checkpoint list.

§block: SemanticBlockVerifier<S, V>

The full semantic block verifier, used for blocks after max_checkpoint_height.
