Crate cloudevents[−][src]

Expand description

This crate implements the CloudEvents Spec for Rust.

use cloudevents::{EventBuilder, AttributesReader, EventBuilderV10};
use chrono::{Utc, DateTime};
use url::Url;

let event = EventBuilderV10::new()
    .id("my_event.my_application")
    .source("http://localhost:8080")
    .ty("example.demo")
    .time(Utc::now())
    .build()?;

println!("CloudEvent Id: {}", event.id());
match event.time() {
    Some(t) => println!("CloudEvent Time: {}", t),
    None => println!("CloudEvent Time: None")
}

This crate includes:

The Event data structure, to represent CloudEvent (version 1.0 and 0.3)
The EventBuilder trait and implementations, to create Event instances
The implementation of serde::Serialize and serde::Deserialize for Event to serialize/deserialize CloudEvents to/from JSON
Traits and utilities in message to implement Protocol Bindings
Feature-guarded modules for various Protocol Binding implementations, e.g. actix, reqwest, warp, rdkafka

Feature flags

Cloudevents uses a set of feature flags to conditionally compile only the module associated with the Protocol Binding you need:

actix: Enables the [binding::actix] protocol binding module. This extends the [actix_web::HttpRequest] with a to_event function, the [actix_web::dev::HttpResponseBuilder] with an event function, and implementations for [actix_web::FromRequest] and [actix_web::Responder] in order to take advantage of actix-web’s Extractors and Responders
reqwest: Enables the [binding::reqwest] protocol binding module.
warp: Enables the [binding::warp] protocol binding module.
rdkafka: Enables the [binding::rdkafka] protocol binding module to seamlessly consume/produce cloudevents within Kafka messages.
