Interact is a Rust framework for friendly online introspection of the running program state in an intuitive command-line interactive way.

Interact is useful for server programs that otherwise receive no input. You can use Interact to make your server receive commands using the special prompt from the interact_prompt crate. The commands can be used to browse your server's internal state, modify it, and call method functions that were specified in interact derive attributes.

Using two traits, Access and Deser, Interact exposes types as trait objects, similarly to the Any trait, but with a functionality of reflection. The Access trait allows to probe the fields of structs and enums and modify them. It also allows to iterate arrays, vectors, and maps. It also allows to safely punch through Rc, Arc, and Mutex. The traits can be derived using #[derive(Interact)].

At the prompt side, predictive parsing is used for providing full auto-complete and hinting, while constructing access paths, and while constructing values used in field assignments and function calls.
