Enum EdgeOrData

pub enum EdgeOrData<LABEL> {
    Data,
    Edge(LABEL),
}

Representation of either a labeled edge or the special ‘data’ label.

Used to implement label orders. The Data label is there to support expressing preference between traversing an edge or resolving to the current node.

Edge(LABEL)

Trait Implementations

impl<LABEL: Copy> Clone for EdgeOrData<LABEL>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<LABEL: Debug> Debug for EdgeOrData<LABEL>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<LABEL: Hash> Hash for EdgeOrData<LABEL>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<LABEL: PartialEq> PartialEq for EdgeOrData<LABEL>

fn eq(&self, other: &EdgeOrData<LABEL>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
