Contains

The Contains crate has 2 traits Container and In.

Container

The Container trait can be used to abstract over types that can contain items: Vec<T>, &[T], HashMap<T>, Option<T>, ect. ```rust use contains::Container;

let vec = vec![1, 2, 3, 4, 5]; let range = 0..5; let option = Some(3);

let containers: &[&dyn Container] = &[&vec, &range, &option]; for container in containers { assert!(container.does_contain(&3)); } ```

In

The In trait is the Inverse of the Container trait and represents a type that is in a container. Mainly it reverse the call order by providing the is_in method. ```rust use contains::{Container, In};

let range = 0..5; assert!(range.doescontain(&3)); // using doescontain assert!(3.is_in(&range)); // using in ```
