Struct quic_rpc::server::RpcChannel
source · pub struct RpcChannel<S: Service, C: ServiceEndpoint<S>, SInner: Service = S> {
pub send: C::SendSink,
pub recv: C::RecvStream,
pub map: Arc<dyn MapService<S, SInner>>,
}
Expand description
A channel for requests and responses for a specific service.
This just groups the sink and stream into a single type, and attaches the information about the service type.
Sink and stream are independent, so you can take the channel apart and use them independently.
Fields§
§send: C::SendSink
Sink to send responses to the client.
recv: C::RecvStream
Stream to receive requests from the client.
map: Arc<dyn MapService<S, SInner>>
Mapper to map between S and S2
Implementations§

S: Service,
C: ServiceEndpoint<S>,

sourcepub fn new(send: C::SendSink, recv: C::RecvStream) -> Self
pub fn new(send: C::SendSink, recv: C::RecvStream) -> Self
Create a new RPC channel.

sourcepub fn map<SNext>(self) -> RpcChannel<S, C, SNext>
pub fn map<SNext>(self) -> RpcChannel<S, C, SNext>
Map this channel’s service into an inner service.
This method is available if the required bounds are upheld: SNext::Req: IntoSInner::Req + TryFromSInner::Req, SNext::Res: IntoSInner::Res + TryFromSInner::Res,
Where SNext is the new service to map to and SInner is the current inner service.
This method can be chained infintely.

If you want to support concurrent requests, you need to spawn this on a tokio task yourself.

pub async fn rpc_map_err<M, F, Fut, T, R, E1, E2>( self, req: M, target: T, f: F ) -> Result<(), RpcServerError<C>>
A rpc call that also maps the error from the user type to the wire type
This is useful if you want to write your function with a convenient error type like anyhow::Error, yet still use a serializable error type on the wire.

Compared to RpcChannel::server_streaming, with this method the stream creation is via a function that returns a future that resolves to a stream.
