The form of a path factor.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Node(NodePattern)

QuantifiedNode

A node pattern followed by a graph-pattern quantifier.

Fields

pattern: NodePattern

quantifier: Quantifier

Relationship(RelationshipPattern)

Parenthesized

Fields

pattern: Box<PathPattern>

where_clause: Option<Box<Expr>>

quantifier: Option<Quantifier>

Subpath

A parenthesized path factor with a subpath-variable binding.

Fields

binding: Name

pattern: Box<PathPattern>

where_clause: Option<Box<Expr>>

quantifier: Option<Quantifier>

LegacyShortest

A legacy shortestPath(...) or allShortestPaths(...) path factor.

Fields

all: bool

pattern: Box<PathPattern>

Error(ErrorNode)
