HandlerServer returns a StreamServer that handles incoming streams using the provided handler.

ListenAndServe starts an jsonrpc2 server on the given address.

NewConn creates a new connection object around the supplied stream.

NewStream returns a Stream built on top of an io.Reader and io.Writer The messages are sent with no wrapping, and rely on json decode consistency to determine message boundaries.

Conn is a JSON RPC 2 client server connection.

Error represents a structured error in a Response.

ID is a Request identifier.

Request is sent to a server to represent a Call or Notify operaton.

Handler is the interface used to hook into the message handling of an rpc connection.

Stream abstracts the transport mechanics from the JSON RPC protocol.

A StreamServer is used to serve incoming jsonrpc2 clients communicating over a newly created stream.

Direction is used to indicate to a logger whether the logged message was being sent or received.

The ServerFunc type is an adapter that implements the StreamServer interface using an ordinary function.
