Trait BackendReceiver

Source 
pub trait BackendReceiver: Send + 'static {

Expand description

Something that can receive bytes.

Required Methods§

Source

fn receive( &self, ) -> Pin<Box<dyn Future<Output = Option<Result<Vec<u8>, BackendError>>> + Send + 'static>>

Hand back the next message each time it’s called. If this emits a BackendError, we’ll stop asking for messages. If it emits None, then the connection has been closed gracefully. The bytes given back should deserialize to a valid JSON-RPC object.
