Hello,

I have the same issue now, tried using different futures versions, now having Cargo.toml as:

[dependencies]
futures = "0.1.16"
grpcio = { version = "0.13", features = ["openssl"] }
protobuf = "~2"

[build-dependencies]
futures = "0.1.16"
protoc-grpcio = "1.0.2"
protobuf-parse = "3.2.0"

Manually changing where F: ::futures::Future<Item = (), Error = ()> to where F: std::future::Future<Output = ()> fixed the issue. Can anyone have a look into that? Should I change some version of some crates?
