Struct Fun 

pub struct Fun {
    pub code: Core,
    pub captures: Vec<OpId>,
}

A function an operator applies per element, closed over the plan nodes it reads.

The captures are why this is not simply a Core lambda: lambda t: t.owner == session.actor reads the session, which is a node — so the operator has to be re-run wholesale when a capture changes, and per element when only the collection changed. Both are expressible only if the captured nodes are named.

Fields

code: Core

Lam over the captured nodes’ variables followed by the element.

captures: Vec<OpId>
