srad

srad is a Sparkplug edge node and application development framework in Rust.

Additional information for this crate can be found in the docs.

Overview

srad aims to make it easy as possible to build reliable, fast, and resource efficient Sparkplug B Edge Nodes and Applications with minimal overhead.

Getting Started

Examples

A simple Edge Node

use srad::{client_rumqtt, eon::{EoN, EoNBuilder, NoMetricManager}};

#[tokio::main]
async fn main() {

    let opts = client_rumqtt::MqttOptions::new("foo:bar", "localhost", 1883);
    let (eventloop, client) = client_rumqtt::EventLoop::new(opts, 0);

    let (mut eon, handle) = EoNBuilder::new(eventloop, client)
        .with_group_id("foo")
        .with_node_id("bar")
        .with_metric_manager(NoMetricManager::new())
        .build().unwrap();

    eon.run().await;
}

A simple Application

use srad::app::{SubscriptionConfig, generic_app::Application};
use srad::client_rumqtt;

#[tokio::main]
async fn main() {
    let opts = client_rumqtt::MqttOptions::new("foo", "localhost", 1883);
    let (eventloop, client) = client_rumqtt::EventLoop::new(opts, 0);
    let (mut application, client) = Application::new("foo", eventloop, client, SubscriptionConfig::AllGroups);
    application.run().await
}

More examples can be found in the examples and in the docs.
