Trait Label

pub trait Label
where
    Self: Sized + Copy + Eq + Hash + Debug,
{
    type Index: Eq + Copy + Hash + Debug + Index + 'static;

    // Required methods
    fn variants() -> &'static [Self];
    fn indexes(&self) -> &'static [Self::Index];
    fn ordinal(&self) -> usize;
    fn name(&self) -> &'static str;
}

A label for an Element. This can be either a vertex or an edge.

Required Associated Types

type Index: Eq + Copy + Hash + Debug + Index + 'static

Information about indexes for this label

Required Methods

fn variants() -> &'static [Self]

All label variants

fn indexes(&self) -> &'static [Self::Index]

The indexes associated with this label

fn ordinal(&self) -> usize

A unique ordinal for this label

fn name(&self) -> &'static str

The name of the label

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
