Trait Contains 

pub trait Contains<I> {
    // Required method
    fn contains(&self, item: I) -> bool;
}

Types for values that contain items.

At present, these are:

type	contains
&str, String	&str, char, &[char] F: FnMut(char) -> bool
Vec<T>	T, &T
Option<T>	I where T: Contains<I>
form::Result<'_, T>	I where T: Contains<I>

Required Methods

fn contains(&self, item: I) -> bool

Returns true if self contains item.
