A rust client for dgraph

The client used the grpc channel & api of dgraph.

What is dgraph ?

from dgraph site:

Dgraph is an open source, horizontally scalable and distributed graph database, providing ACID transactions, consistent replication and linearizable reads. It's built from ground up to perform for a rich set of queries. Being a native graph database, it tightly controls how the data is arranged on disk to optimize for query performance and throughput, reducing disk seeks and network calls in a cluster.

Dgraph's goal is to provide Google production level scale and throughput, with low enough latency to be serving real time user queries, over terabytes of structured data. Dgraph supports GraphQL-like query syntax, and responds in JSON and Protocol Buffers over GRPC and HTTP.

Samples

see examples

examples/dgraph_tuto01

Sample adpated from go sample at https://docs.dgraph.io/clients/

```sh

launch dgraph (grpc on localhost:9080)

see doc of dgraph

run

cargo run --example dgraph_tuto01 ```

Build

The lib used grpcio to generate the rust code from grpc's proto file.

sh cargo build

Update the grpc client

```sh

install grpcio

get api.proto & generate client

cd src curl -O https://github.com/dgraph-io/dgraph/raw/v1.0.2/protos/api.proto protoc --rustout=. --grpcout=. --plugin=protoc-gen-grpc=which grpc_rust_plugin api.proto
