Struct EdgeData 

pub struct EdgeData {
    pub variable: Option<String>,
    pub rel_type: Option<String>,
    pub properties: HashMap<String, CypherValue>,
}

Data stored at each edge in the graph built by build_graph_from_cypher.

Fields

variable: Option<String>

Bound variable name from the Cypher pattern (e.g. "r"), if present.

rel_type: Option<String>

Relationship type (e.g. "KNOWS"), if specified.

properties: HashMap<String, CypherValue>

Properties specified in the relationship pattern.

Trait Implementations

impl Clone for EdgeData

fn clone(&self) -> EdgeData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CypherEdge for EdgeData

fn has_rel_type(&self, rel_type: &str) -> bool

Returns whether this edge matches the requested relationship type.

fn rel_type(&self) -> Option<&str>

Return the relationship type, if any.

fn from_cypher( variable: Option<String>, rel_type: Option<String>, properties: HashMap<String, CypherValue>, ) -> Self

Construct an edge value from a Cypher pattern.

impl CypherProperties for EdgeData

fn get(&self, name: &str) -> Option<&CypherValue>

Get a property value by name.

fn properties(&self) -> HashMap<String, CypherValue>

Return all properties as a cloned map for query results.

impl Debug for EdgeData

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

Formats the value using the given formatter.

impl PartialEq for EdgeData

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