Trait phron_finality::sync::ChainStatusNotifier

pub trait ChainStatusNotifier<H: Header> {
    type Error: Debug + Display;

    // Required method
    fn next<'life0, 'async_trait>(
        &'life0 mut self
    ) -> Pin<Box<dyn Future<Output = Result<ChainStatusNotification<H>, Self::Error>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

A stream of notifications about the chain status in the database changing. We assume that this will return all the events, otherwise we will end up with a broken state.

Required Associated Types

fn next<'life0, 'async_trait>( &'life0 mut self ) -> Pin<Box<dyn Future<Output = Result<ChainStatusNotification<H>, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Returns a chain status notification when it is available. This method’s implementation must be cancellation safe.
