## What is it?

Hedwig is a inter-service communication bus that works on AWS and GCP, while keeping things pretty
simple and straight forward.

It allows validation of the message payloads before they are sent, helping to catch cross-component
incompatibilities early.

Hedwig allows separation of concerns between consumers and publishers so your services are loosely
coupled, and the contract is enforced by the message payload validation. Hedwig may also be used to
build asynchronous APIs.

## Quick Start

### Installation

Add to Cargo.toml:

```toml
[dependencies]
hedwig = "6"
```

You may also need to enable additional features in order to use the optional publishers or
validators, like this:

```toml
[dependencies]
hedwig = { version = "6", features = ["google"] }
```

### Usage

See [the examples](https://github.com/standard-ai/hedwig-rust/tree/master/examples) in the
repository as well as [the crate-level documentation](https://docs.rs/hedwig/) for
usage examples.
