Implementation of gRPC Logging Middleware, integrating [Zerolog](https://github.com/rs/zerolog) as a gRPC [Interceptor](https://github.com/grpc-ecosystem/go-grpc-middleware) to log the following fields:

- Request Protobufs as JSON.
- Response Protobufs as JSON, or Errors.
- Status Code, Duration, Timestamp, Service Name, Service Method, IP, Metadata Fields and User Agent.

## Usage

```go
import (
	"github.com/philip-bui/grpc-zerolog"
)

func main() {
	// With global Zerolog logger.
	grpc.NewServer(
		zerolog.UnaryInterceptor(),
	)

	// With custom Zerolog instance.
	log := zerolog.New(os.Stdout)
	grpc.NewServer(
		zerolog.UnaryInterceptorWithLogger(&log),
	)
}
```
