Struct vapcore_snapshot::Watcher

pub struct Watcher { /* fields omitted */ }

A ChainNotify implementation which will trigger a snapshot event at certain block numbers.

Implementations

impl Watcher

pub fn new<F, C>(
    client: Arc<dyn BlockInfo>,
    sync_status: F,
    channel: IoChannel<ClientIoMessage<C>>,
    period: u64,
    history: u64
) -> Self where
    F: 'static + Send + Sync + Fn() -> bool,
    C: 'static + Send + Sync, 

Create a new Watcher which will trigger a snapshot event once every period blocks, but only after that block is history blocks old.

fn new_blocks(&self, new_blocks: NewBlocks)

fires when chain has new blocks.

pub fn start(&self)

fires when chain achieves active mode

pub fn stop(&self)

fires when chain achieves passive mode

pub fn broadcast(&self, _message_type: ChainMessageType)
