Function tool::empty::non_empty

pub fn non_empty<T: ?Sized + IsEmpty>(value: &T) -> bool

False if the value is "empty"

Shortcut for |x|{ !empty(x) }.

Example:

use tool::non_empty;
let strings: Vec<_> = vec!["my string", "", "asdf", ""]
    .into_iter()
    .filter(non_empty)
    .collect();
assert_eq!(strings, vec!["my string", "asdf"]);
