Struct EdgeExpansionBuilder 

pub struct EdgeExpansionBuilder { /* private fields */ }

Chained builder for an edge-projecting expansion slot. Returned by QueryBuilder::traverse_edges; call Self::done to append the slot to the parent QueryBuilder and resume chaining.

Implementations

impl EdgeExpansionBuilder

pub fn edge_filter(self, predicate: Predicate) -> Self

Attach an edge-property predicate. Only EdgePropertyEq and EdgePropertyCompare are valid here; other variants are accepted by the AST but will be rejected downstream during edge-expansion compilation.

pub fn endpoint_filter(self, predicate: Predicate) -> Self

Attach an endpoint-node predicate (applied to the target node on Out traversal, source node on In).

pub fn done(self) -> QueryBuilder

Finalize the edge-expansion slot and return the parent QueryBuilder for further chaining.

Trait Implementations

impl Clone for EdgeExpansionBuilder

fn clone(&self) -> EdgeExpansionBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeExpansionBuilder

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

Formats the value using the given formatter.

impl PartialEq for EdgeExpansionBuilder

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