Trait to use the full functionality of jsonrpseee Subscription type without actually enforcing it.

Required Methods

fn next<'life0, 'async_trait>( &'life0 mut self ) -> Pin<Box<dyn Future<Output = Option<Result<Notification>>> + 'async_trait>>

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

Returns the next notification from the stream. This may return None if the subscription has been terminated, which may happen if the channel becomes full or is dropped.

Note: This has an identical signature to the [StreamExt::next] method (and delegates to that). Import [StreamExt] if you’d like access to other stream combinator methods.

fn unsubscribe<'async_trait>( self ) -> Pin<Box<dyn Future<Output = Result<()>> + 'async_trait>>

where Self: 'async_trait,

Unsubscribe and consume the subscription.
