[−][src]Trait lhlist::Label

pub trait Label {
    type AssocType;
    type Uid: Unsigned;

    const NAME: &'static str;
    fn name() -> &'static str { ... }

    fn id() -> usize { ... }
}

A trait with information about a label.

Typically, labels are simply unit-like structs used to identify elements in a list. This trait contains the label's name, an associated type, and an internal identifier.

It is encouraged that this trait be implemented using the new_label macro or the #[label] attribute, which ensures that the identifier Uid is unique. See the documentation for new_label for examples.
