Struct RelatedExpr 

pub struct RelatedExpr {
    pub target_labels: Vec<String>,
    pub alias: Option<String>,
    pub rel_type: Option<String>,
    pub direction: Direction,
    pub hops: Option<(u64, u64)>,
    pub cycle: bool,
    pub filter: Option<Box<Expr>>,
}

Traversal predicate mirroring the documented relationship syntax.

Fields

target_labels: Vec<String>

Labels an endpoint record must carry (empty = any label).

alias: Option<String>

Optional $alias binding for the endpoint, used by $count/$sum/$collect.

rel_type: Option<String>

Relationship type filter; None matches every relation type.

direction: Direction

Edge direction to traverse.

hops: Option<(u64, u64)>

Variable-length traversal bounds (min, max); absent = one hop.

cycle: bool

$cycle: true when the traversal must return to the start record.

filter: Option<Box<Expr>>

Predicates evaluated on the endpoint record (may nest further RelatedExpr children for multi-level blocks).
