Enum Direction 

pub enum Direction {
    Outgoing,
    Incoming,
    Both,
}

Direction for graph traversal.

Specifies which edges to follow when traversing from a node.

Variants

Outgoing

Follow outgoing edges (source -> target).

When traversing from node A, find nodes B where an edge A -> B exists.

Incoming

Follow incoming edges (target <- source).

When traversing from node A, find nodes B where an edge B -> A exists.

Both

Follow edges in both directions.

When traversing from node A, find nodes B where either A -> B or B -> A exists.

Implementations

impl Direction

pub const fn includes_outgoing(self) -> bool

Returns true if this direction includes outgoing edges.

pub const fn includes_incoming(self) -> bool

Returns true if this direction includes incoming edges.

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Direction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Direction

impl Debug for Direction

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

Formats the value using the given formatter.

impl Default for Direction

fn default() -> Direction

Returns the “default value” for a type.

impl Eq for Direction

impl Hash for Direction

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 PartialEq for Direction

fn eq(&self, other: &Direction) -> 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.
