Struct ckb_chain::chain::ChainController

pub struct ChainController { /* private fields */ }

Controller to the chain service.

The controller is internally reference-counted and can be freely cloned.

A controller can invoke ChainService methods.

Implementations

impl ChainController

pub fn new( process_block_sender: Sender<Request<(Arc<BlockView>, Switch), Result<bool, Error>>>, truncate_sender: Sender<Request<Byte32, Result<(), Error>>>, stop: StopHandler<()> ) -> Self

pub fn process_block(&self, block: Arc<BlockView>) -> Result<bool, Error>

Inserts the block into database.

Expects the block’s header to be valid and already verified.

If the block already exists, does nothing and false is returned.

BlockVerifier NonContextualBlockTxsVerifier ContextualBlockVerifier will performed

pub fn internal_process_block( &self, block: Arc<BlockView>, switch: Switch ) -> Result<bool, Error>

Internal method insert block for test

switch bit flags for particular verify, make easier to generating test data

pub fn truncate(&self, target_tip_hash: Byte32) -> Result<(), Error>

Truncate chain to specified target

Should use for testing only

pub fn try_stop(&mut self)

pub fn non_owning_clone(&self) -> Self

Since a non-owning reference does not count towards ownership, it will not prevent the value stored in the allocation from being dropped

Trait Implementations

impl Clone for ChainController

fn clone(&self) -> ChainController

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Drop for ChainController

fn drop(&mut self)

Executes the destructor for this type.
