Struct PathMatchResult 

pub struct PathMatchResult {
    pub nodes: Vec<EntityId>,
    pub step_edges: Vec<Vec<EdgeId>>,
}

Result of a path pattern match.

Fields

nodes: Vec<EntityId>

The nodes traversed, in order.

step_edges: Vec<Vec<EdgeId>>

The edges used for each step. Each inner vector contains edges for one step (may have multiple for variable-length steps).

Implementations

impl PathMatchResult

pub fn new(nodes: Vec<EntityId>, step_edges: Vec<Vec<EdgeId>>) -> Self

Create a new path match result.

pub fn source(&self) -> Option<EntityId>

Get the starting node.

pub fn target(&self) -> Option<EntityId>

Get the ending node.

pub fn all_edges(&self) -> Vec<EdgeId>

Get all edges as a flat list.

pub fn length(&self) -> usize

Get the total path length (number of edges).

Trait Implementations

impl Clone for PathMatchResult

fn clone(&self) -> PathMatchResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PathMatchResult

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

Formats the value using the given formatter.

impl From<PatternMatch> for PathMatchResult

fn from(pm: PatternMatch) -> Self

Converts to this type from the input type.

impl PartialEq for PathMatchResult

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