source · 
pub struct RequestResponsesBehaviour { /* private fields */ }
Expand description

Implementation of NetworkBehaviour that provides support for request-response protocols.

Implementations§

source§

impl RequestResponsesBehaviour

source

pub fn new( list: impl Iterator<Item = ProtocolConfig>, peer_store: Arc<dyn PeerStoreProvider>, ) -> Result<Self, RegisterError>

Creates a new behaviour. Must be passed a list of supported protocols. Returns an error if the same protocol is passed twice.

source

pub fn send_request( &mut self, target: &PeerId, protocol_name: ProtocolName, request: Vec<u8>, fallback_request: Option<(Vec<u8>, ProtocolName)>, pending_response: Sender<Result<(Vec<u8>, ProtocolName), RequestFailure>>, connect: IfDisconnected, )

Initiates sending a request.

If there is no established connection to the target peer, the behavior is determined by the choice of connect.

An error is returned if the protocol doesn’t match one that has been registered.
