# isnt This crate contains extension methods for most boolean-valued functions the standard library. For example ```rust fn f(x: *const u8, y: u8, z: &[u8]) -> bool { x.is_not_null() && y.is_not_ascii() && z.is_not_empty() } ``` Most of the code in this crate is generated and undocumented. The organization follows the module structure of the standard library.
