Struct ethcore::snapshot::Watcher

pub struct Watcher { /* fields omitted */ }

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

Methods

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.
