Enum ConstraintScope 

pub enum ConstraintScope {
    Node(String),
    Relationship(String),
}

Scope a constraint applies to. Node(label) covers every node carrying the label; Relationship(edge_type) covers every edge with the given type. Kept as an enum rather than a plain string so future scope extensions (e.g. specific pattern shapes) land additively.

Variants

Node(String)

Relationship(String)

Implementations

impl ConstraintScope

pub fn target(&self) -> &str

The scope’s target string — label for node scope, edge type for relationship scope. Handy when the caller has already dispatched on the variant and just needs the name.

pub fn name_tag(&self) -> &'static str

Short tag used to disambiguate auto-generated constraint names so a node and a relationship constraint on the same target-and-property don’t collide.

Trait Implementations

impl Clone for ConstraintScope

fn clone(&self) -> ConstraintScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstraintScope

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

Formats the value using the given formatter.

impl Hash for ConstraintScope

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ConstraintScope

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