This is a package for [CERK](https://github.com/ce-rust/cerk).
CERK is an open source [CloudEvents](https://github.com/cloudevents/spec) Router written in Rust with a MicroKernel architecture.
## Introduction
CERK lets you route your [CloudEvents](https://github.com/cloudevents/spec) between different different ports.
Ports are transport layer bindings over which CloudEvents can be exchanged.
It is built with modularity and portability in mind.
## Components
CERK comes with a couple of prefabricated components, but implementing custom components is easy.
A good overview is provided on [GitHub](https://github.com/ce-rust/cerk/).
## This Component: File Based Config Loader
This port loads configurations from a json file.
The file path could be set with the env variable `CONFIG_PATH`, default is `./config.json`.
### Example Config
```json
{
"routing_rules": [
"dummy-logger-output"
],
"ports": {
"ampq-input": {
"uri": "amqp://127.0.0.1:5672/%2f",
