rust - 如何解决此错误：错误[E0277]：不满足特征绑定`SocketStream：std :: io :: Read`？

Question

let stream = match address.connect().wait(wait_scope, (&mut event_port)) {
            Ok(s) => s,
            Err(e) => panic!("Error connecting to addr: {:?}", e),
        };
let network = Box::new(capnp_rpc::twoparty::VatNetwork::new(
            stream.clone(),
            stream,
            rpc_twoparty_capnp::Side::Client,
            Default::default(),
        ));

这是代码体。我正在使用 capnp::rpc 版本 0.8.3。“ std::io::Read SocketStream`std::io::Write没有实现该特征”我想我需要以某种方式将std::io::Read和Write添加到我创建的流中。我怎样才能做到这一点？SocketStream " "the trait is not implemented for
