Katasec.DStream.Plugin 0.0.5

Katasec.DStream.Plugin

.NET library for building DStream-compatible plugins using gRPC and the HashiCorp go‑plugin protocol.

Enable seamless integration of C# plugin components with the DStream CLI, leveraging the same Terraform-style plugin framework used by HashiCorp tools.

🚀 Getting Started

Prerequisites

• .NET 9.0 SDK or later
• DStream CLI (Go) installed and available on your PATH
• plugin.proto definitions (included in this package)

Installation

dotnet add package Katasec.DStream.Plugin

🛠️ Usage

Implementing a plugin

using static Katasec.DStream.Plugin.Plugin;
using Google.Protobuf.WellKnownTypes;
using Grpc.Core;

public class MyPlugin : PluginBase, IDStreamPlugin
{
    public override Task<GetSchemaResponse> GetSchema(Empty request, ServerCallContext context)
    {
        // Your implementation here
    }

    // Implement other RPC methods...
}

Running the plugin

var host = new DStreamPluginHost<MyPlugin>("my-plugin-id", new MyPlugin());
host.Run(); // Or host.RunAsync(CancellationToken)

Check the Examples/ folder for a fully working example.
