Struct RelPattern 

pub struct RelPattern {
    pub var: Option<String>,
    pub types: Vec<String>,
    pub direction: Direction,
    pub min_hops: Option<u32>,
    pub max_hops: Option<u32>,
    pub properties: Option<Expr>,
    pub span: Span,
}

A relationship pattern: -[var:TYPE*min..max {props}]->.

Fields

var: Option<String>

types: Vec<String>

Relationship type constraints.

direction: Direction

min_hops: Option<u32>

Minimum hops for variable-length patterns (None = exactly 1).

max_hops: Option<u32>

Maximum hops (None = unbounded or exactly 1 if min_hops is also None).

properties: Option<Expr>

span: Span
