Detailed Description

The InputScheme represents a type of fetcher. Each fetcher registers with nix at startup time. When processing an input for a flake, each scheme is given an opportunity to "recognize" that input from the url or attributes in the flake file's specification and return an Input object to represent the input if it is recognized. The Input object contains the information the fetcher needs to actually perform the "fetch()" when called.
