Enum WrappedCollection

Source
pub enum WrappedCollection<T> {
    NoWrapping(T),
    Parentheses(T),
}
Expand description

Helper to indicate if a collection should be wrapped by a symbol in the display form

Display is implemented for every Vec<T> where T: Display. The string output is a comma separated list for the vec items

§Examples

let items = WrappedCollection::Parentheses(vec!["one", "two", "three"]);
assert_eq!("(one, two, three)", items.to_string());

let items = WrappedCollection::NoWrapping(vec!["one", "two", "three"]);
assert_eq!("one, two, three", items.to_string());

Variants§

§

NoWrapping(T)

Print the collection without wrapping symbols, as item, item, item

§

Parentheses(T)

Wraps the collection in Parentheses, as (item, item, item)
