Struct RelationshipPattern 

pub struct RelationshipPattern {
    pub variable: Option<String>,
    pub rel_types: Vec<String>,
    pub direction: RelDirection,
    pub properties: Option<MapLiteral>,
    pub min_hops: Option<u32>,
    pub max_hops: Option<u32>,
}

A relationship pattern: -[variable:TYPE {props}]->.

Fields

variable: Option<String>

Optional variable binding.

rel_types: Vec<String>

Relationship type filters.

direction: RelDirection

Arrow direction.

properties: Option<MapLiteral>

Optional inline property map.

min_hops: Option<u32>

Minimum hops for variable-length paths. None means regular 1-hop.

max_hops: Option<u32>

Maximum hops for variable-length paths. None means unbounded (capped by planner).

Trait Implementations

impl Clone for RelationshipPattern

fn clone(&self) -> RelationshipPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelationshipPattern

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

Formats the value using the given formatter.

impl PartialEq for RelationshipPattern

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