Since announcement of new rust driver I am using latest git repository head in my personal project. I just noticed that when I am running my e2e tests concurrently client instance is getting corrupted and I can't make any query afterwards. 

 

Error { kind: ResponseError

{ message: \"expected a field of type `n`\" }

}"

Error { kind: ResponseError

{ message: \"expected a field of type `cursor`\"}

}"

Error { kind: ResponseError

{ message: \"expected a field of type `nModified`\" }

}"
