Constant grpcio_sys::grpc_status_code::GRPC_STATUS_DEADLINE_EXCEEDED

pub const GRPC_STATUS_DEADLINE_EXCEEDED: Type = 4;

Deadline expired before operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully. For example, a successful response from a server could have been delayed long enough for the deadline to expire.
