//! # yn //! //! Want to check if a value is yes, no, maybe both? Maybe you want to check if a value is somewhat yes? Somewhat no? //! //! We've got you covered! This is state of the art.. EHEM.. Natural language processing. With yn, you will be the one who can safely say NO! //! //! ## Examples //! //! If you want to use this very advanced natural language processing technology you simply need to do the following: //! //! To check if something is yes: //! //! ```rust //! extern crate yn; //! //! assert!(yn::yes("yes")); // this is yes, you can be 100% sure //! ``` //! //! If you don't have time to write yes: //! //! ```rust //! extern crate yn; //! //! assert!(yn::yes("y")); // this is also yes //! ``` //! //! If you're a bleepity blooping machine: //! //! ```rust //! extern crate yn; //! //! assert!(yn::yes("1")); //! ``` //! //! Of course, this is not yes: //! //! ```rust //! extern crate yn; //! //! assert!(!yn::yes("no")); //! ``` //! //! You can also check if something is somewhat yes: //! //! ```rust //! extern crate yn; //! //! assert!(yn::is_somewhat_yes("this has a y so it is the word")); //! ``` //! Or if you want to check if something just contains y: //! //! ```rust //! extern crate yn; //! //! assert!(yn::is_kinda_yes("very much so")); //! ``` //! //! The options are endless. Your imagination is the limit. //! //! ## License //! //!
