CloudEvents SDK Rust

This project implements the CloudEvents Spec for Rust.

Note: This project is WIP under active development, hence all APIs are considered unstable.

Spec support

Crate Structure

The core modules include definitions for the Event and EventBuilder data structures, JSON serialization rules, and a mechanism to support various Protocol Bindings, each of which is enabled by a specific feature flag:

• actix: Integration with actix.
• axum: Integration with axum.
• warp: Integration with warp.
• reqwest: Integration with reqwest.
• rdkafka: Integration with rdkafka.
• nats: Integration with nats

This crate is continuously tested to work with GNU libc, WASM and musl toolchains.

Get Started

To get started, add the dependency to Cargo.toml, optionally enabling your Protocol Binding of choice:

[dependencies]
cloudevents-sdk = { version = "0.7.0" }

Now you can start creating events:

use cloudevents::{EventBuilder, EventBuilderV10};
use url::Url;

let event = EventBuilderV10::new()
    .id("aaa")
    .source(Url::parse("http://localhost").unwrap())
    .ty("example.demo")
    .build()?;

Checkout the examples using our integrations to learn how to send and receive events:

• Actix Web Example
• Axum Example
• Reqwest/WASM Example
• Kafka Example
• Warp Example
• NATS Example

Community

• There are bi-weekly calls immediately following the Serverless/CloudEvents call at 9am PT (US Pacific). Which means they will typically start at 10am PT, but if the other call ends early then the SDK call will start early as well. See the CloudEvents meeting minutes to determine which week will have the call.

Each SDK may have its own unique processes, tooling and guidelines, common governance related material can be found in the CloudEvents community directory. In particular, in there you will find information concerning how SDK projects are managed, guidelines for how PR reviews and approval, and our Code of Conduct information.
