Struct Edge 

pub struct Edge {
    pub id: EdgeId,
    pub from: PortRef,
    pub to: PortRef,
    pub when: Option<Expr>,
    pub transform: Option<Expr>,
    pub as_name: Option<Symbol>,
    pub priority: i64,
    pub max_visits: Option<u32>,

    pub metadata: Vec<(Symbol, Expr)>,
}

A directed route from one node port to another node port.

Fields

id: EdgeId

Stable edge id.

from: PortRef

Source node port. Omitted source ports normalize to out.

to: PortRef

Destination node port. Omitted destination ports normalize to in.

when: Option<Expr>

Optional edge predicate expression.

transform: Option<Expr>

Optional transform expression applied while routing.

as_name: Option<Symbol>

Optional wrapper key for the routed value.

priority: i64

Deterministic routing priority.

max_visits: Option<u32>

Optional per-edge visit cap.

buffer: Option<Expr>

Optional buffer policy expression.

metadata: Vec<(Symbol, Expr)>

Extra edge metadata.
