Required Methods

fn iter(&self) -> Result<Box<dyn NameIter>>

Iterate through the set in defined order.

fn iter_rev(&self) -> Result<Box<dyn NameIter>>

Iterate through the set in the reversed order.

fn count(&self) -> Result<u64>

Number of names in this set.

fn first(&self) -> Result<Option<Vertex>>

The first name in the set.

fn last(&self) -> Result<Option<Vertex>>

The last name in the set.

fn is_empty(&self) -> Result<bool>

Test if this set is empty.

fn contains(&self, name: &Vertex) -> Result<bool>

Test if this set contains a given name.

fn as_any(&self) -> &dyn Any

For downcasting.

fn hints(&self) -> &Hints

Get or set optimization hints.

fn id_convert(&self) -> Option<&dyn IdConvert>

Get an optional IdConvert interface to check hints.
