Unable to run examples

[frostyplanet]

I have my local etcd container running, but almost all the examples and tests fail:

$ cargo run --example lock
   Compiling etcd-client v0.6.5 (/home/plan/projects/qingcloud/etcd-client)
    Finished dev [unoptimized + debuginfo] target(s) in 5.18s
     Running `target/debug/examples/lock`
try to lock with name 'lock-test'
Error: GRpcStatus(Status { code: Unimplemented, message: "unknown service v3lockpb.Lock", metadata: MetadataMap { headers: {"content-type": "application/grpc"} } })

what's the version of your etcd server?

[frostyplanet]

docker running etcd 3.1.4.
I previously use luncj/etcd-rs and I'd like to try this project out, it seams have more throughout unit test.

[davidli2010]

The proto files are copied from etcd 3.4, and we test this library with etcd 3.4.

[frostyplanet]

Diff between proto in luncj/etcd-rs , I don't see much difference aside from comment and intention.
I suspect the failure in example is related to tonic the grpc library (but I don't know alot about it)

[davidli2010]

You can upgrade your etcd to 3.4 and try again.

Check your endpoints.
You should connect to port 2379, not 2380!
