+ProSA is a merge of multiple [Worldline](https://worldline.com/) internal product concepts caviarized to be released as a [🦀 Rust](https://www.rust-lang.org/) open-source.
 The library aimed at providing a simple and lightweight protocol service adaptor for service oriented architectures.
 The goal of this project is to provide a flexible and scalable platform for developing and deploying microservices, allowing developers to focus on writing business logic while ProSA takes care of the underlying infrastructure concers.
