Rust CDEvents SDK

June 25, 2026 · View on GitHub

Rust SDK to emit CDEvents.

The SDK can be used to create CDEvents and send them as CloudEvents, as well as parse a received CloudEvent into a CDEvent.

Create and send your first CDEvent as CloudEvent

Import the modules in your code

cdevents-sdk = "0.4"

To send a CDEvent as CloudEvent:

// from examples/pipelinerun_finished.rs
use std::error::Error;

use cdevents_sdk::{CDEvent, Subject, spec_0_5_1::pipelinerun_finished};
use cloudevents::{Event, AttributesReader};

fn main() -> Result<(), Box<dyn Error>> {
    let cdevent = CDEvent::from(
        Subject::from(pipelinerun_finished::Content{
            errors: Some("pipelineErrors".into()),
            outcome: Some(pipelinerun_finished::ContentOutcome::Success),
            pipeline_name: Some("testPipeline".into()),
            uri: Some("https://dev.pipeline.run/url".try_into()?)
        })
        .with_id("/dev/pipeline/run/1".try_into()?)
        .with_source("https://dev.pipeline.run/source".try_into()?)
    )
    .with_id("271069a8-fc18-44f1-b38f-9d70a1695819".try_into()?)
    .with_source("https://dev.cdevents".try_into()?)
    ;

    let cdevent_expected = cdevent.clone();

    // shortcut for creating cloudevents with
    //
    // ```rust
    // use cloudevents::event::EventBuilderV10;
    // use cdevents_sdk::cloudevents::BuilderExt;
    //
    // let mut cloudevent = EventBuilderV10::new().with_cdevent(cdevent.clone())?.build()?;
    // ```
    let cloudevent: Event = cdevent.try_into()?;

    // zero transport, but cloning
    let cloudevent_received: Event = cloudevent.clone();
    let cdevent_extracted: CDEvent = cloudevent_received.try_into()?;

    assert_eq!(cloudevent.id(), cdevent_extracted.id().to_string());
    assert_eq!(cdevent_expected, cdevent_extracted);
    Ok(())
}

See the CloudEvents docs as well.
