Struct ethcore::snapshot::Watcher

pub struct Watcher { /* private fields */ }

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

Implementations

impl Watcher

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

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