Enum TraversalDirection 

pub enum TraversalDirection {
    Outgoing,
    Incoming,
    Both,
}

Slice 20 (G5) — direction of graph traversal for Engine::graph_neighbors / Engine::search_expand.

Outgoing follows edges where the root is the from_id (source). Incoming follows edges where the root is the to_id (target). Both follows edges in either direction.

Trait Implementations

impl Clone for TraversalDirection

fn clone(&self) -> TraversalDirection

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Copy for TraversalDirection

impl Debug for TraversalDirection

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

impl Eq for TraversalDirection

impl PartialEq for TraversalDirection

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