SEP2 Client Library

sep2_client is a (WIP) Rust library for developing IEEE 2030.5 compliant clients on Linux[^1] based operating systems.

It relies on, and should be used alongside, the sep2_common crate, and it's implementation of the IEEE 2030.5 XSD.

This crate uses async rust, and currently only supports the tokio runtime.

Core Features

  • Application Support Function Set (TCP, HTTP)
  • Security Function Set (TLS + Certificate Verification, HTTPS)
  • IEEE 2030.5 Base Client Capabilities (GET, POST, PUT, DELETE)
  • Asynchronous Resource Polling
  • Notification / Subscription Client Server Mechanism
  • Global Time Offset (Server Time Sync)
  • Event Scheduler
    • DER
    • DRLC
    • Messaging
    • Pricing
    • Per-Schedule Time Offset
  • Tests / Documentation
    • IEEE 2030.5 Examples as System Tests
    • Event Scheduler Tests
    • Subscription/Notification Tests
    • DER Non-Aggregate Client Sample Impl.
  • Australian CSIP Extensions

Future

Examples

A client that synchronises it's time with the server:

use sep2_client::{client::Client, time::update_time_offset};
use sep2_common::packages::{dcap::DeviceCapability, time::Time};

#[tokio::main]
async fn main() {
    // Create a HTTPS client for a specific server
    let client = Client::new_https(
        "https://127.0.0.1:1337",
        "client_cert.pem",
        "client_private_key.pem",
        "serca.pem",
        // No KeepAlive
        None,
        // Default Poll Tick Rate (10 minutes)
        None,
    )
    .expect("Couldn't create client");
    let dcap = client
        .get::<DeviceCapability>("/dcap")
        .await
        .expect("Couldn't retrieve dcap");
    let time_link = &dcap.time_link.unwrap();
    let time = client.get::<Time>(&time_link.href).await.unwrap();
    // Sync client time
    update_time_offset(time);
}

More comprehensive examples can be found in the sep2_client/examples directory.

features = ["der","pubsub"]

Full list of features

  • default: All mandatory IEEE 2030.5 Client function sets. Application Support, Security & Time.
  • event: A Generic Event Schedule interface
  • der: A Scheduler for DER Function Set Events
  • pricing: A Scheduler for Pricing Function Set Events
  • messaging: A Scheduler for Messaging Function Set Events
  • drlc: A Scheduler for DRLC Function Set Events
  • pubsub: A lightweight server for the Subscription / Notification function set.
  • csip_aus: CSIP-AUS Extensions
  • all: All of the above

Dependencies

Due to the security requirements of IEEE 2030.5, this library only supports TLS using OpenSSL. To use this library you will require a local installation of OpenSSL with support for ECDHE-ECDSA-AES128-CCM8.

[^1]: The library happens to performs as expected on macOS. If you would like to test the client locally on macOS, ensure openssl does not refer to libressl, as is the case by default.
