pub struct Synchronizer {
    pub shared: Arc<SyncShared>,
    /* private fields */
}

Sync protocol handle

Fields

shared: Arc<SyncShared>

Sync shared state

Implementations

impl Synchronizer

pub fn new(chain: ChainController, shared: Arc<SyncShared>) -> Synchronizer

Init sync protocol handle

This is a runtime sync protocol shared state, and any relay messages will be processed and forwarded by it

pub fn shared(&self) -> &Arc<SyncShared>

Get shared state

pub fn peers(&self) -> &Peers

Get peers info

pub fn process_new_block(&self, block: BlockView) -> Result<bool, CKBError>

Process a new block sync from other peer

pub fn get_blocks_to_fetch(
    &self,
    peer: PeerIndex,
    ibd: IBDState
) -> Option<Vec<Vec<Byte32>>>

Get blocks to fetch

pub fn eviction(&self, nc: &dyn CKBProtocolContext)

Regularly check and eject some nodes that do not respond in time

Trait Implementations

impl CKBProtocolHandler for Synchronizer

fn init<'life0, 'async_trait>(
    &'life0 mut self,
    nc: Arc<dyn CKBProtocolContext + Sync>
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Init action on service run

fn received<'life0, 'async_trait>(
    &'life0 mut self,
    nc: Arc<dyn CKBProtocolContext + Sync>,
    peer_index: PeerIndex,
    data: Bytes
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Called when the corresponding protocol message is received

fn connected<'life0, 'life1, 'async_trait>(
    &'life0 mut self,
    nc: Arc<dyn CKBProtocolContext + Sync>,
    peer_index: PeerIndex,
    _version: &'life1 str
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,
    'life1: 'async_trait,

Called when opening protocol

fn disconnected<'life0, 'async_trait>(
    &'life0 mut self,
    _nc: Arc<dyn CKBProtocolContext + Sync>,
    peer_index: PeerIndex
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Called when closing protocol

fn notify<'life0, 'async_trait>(
    &'life0 mut self,
    nc: Arc<dyn CKBProtocolContext + Sync>,
    token: u64
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Called when the Service receives the notify task

fn poll<'life0, 'async_trait>(
    &'life0 mut self,
    _nc: Arc<dyn CKBProtocolContext + Sync + 'static>
) -> Pin<Box<dyn Future<Output = Option<()>> + Send + 'async_trait, Global>>where
    'life0: 'async_trait,
    Self: 'async_trait,

Behave like Stream::poll

impl Clone for Synchronizer

fn clone(&self) -> Synchronizer

Returns a copy of the value.

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

Performs copy-assignment from source.
