Roy Thomas Fielding's thesis Architectural Styles and the Design of Network-based Software Architectures describes Representational State Transfer which comprises several core concepts: - Resource: A conceptual mapping to one or more entities. - Representation: An instance of a resource at a given point in time. Async::REST models these abstractions as closely and practically as possible and serves as a basis for building asynchronous web clients. WWW: https://github.com/socketry/async-rest
