Struct RelSpec 

pub struct RelSpec {
    pub types: Vec<SmolStr>,
    pub direction: Direction,
    pub length: RelLength,
    pub properties: Option<Expr>,
}

Specification for the relationship in an expand operator. Spec §12.1.

Fields

types: Vec<SmolStr>

Allowed relationship types (empty = any type).

direction: Direction

Traversal direction.

length: RelLength

Variable-length qualifier.

properties: Option<Expr>

Optional inline property predicate on the relationship.

Trait Implementations

impl Clone for RelSpec

fn clone(&self) -> RelSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelSpec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RelSpec

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl PartialEq for RelSpec

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

impl Serialize for RelSpec

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Eq for RelSpec

impl StructuralPartialEq for RelSpec
