In order to make the IO tasks work better with the Actor model, `otavia`\nis not fully compatible with Netty. Happily, most of the application-layer network protocol codecs in the Netty\necosystem can be easily ported to `otavia`, so we maintain this ecosystem project to port various application-layer\nnetwork protocol codecs from Netty and [Eclipse Vert.x](https://vertx.io/).\n\n- [GitHub - otavia-projects](https://github.com/otavia-projects)\n\n## Contributes\n\nAny contributions are welcome!","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fotavia-projects%2Fotavia","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fotavia-projects%2Fotavia","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fotavia-projects%2Fotavia/lists"}
