Enum Var 

pub enum Var {
    ScopeX,
    ScopeY,
    ScopeZ,
    SplitI,
    SplitN,
    Depth,
    Named(String),
}

Built-in read-only variables.

Variants

ScopeX

Current scope extent along local X (scope.x).

ScopeY

Current scope extent along local Y (scope.y).

ScopeZ

Current scope extent along local Z (scope.z).

SplitI

Zero-based index of this shape within the last Split / Repeat (split.i). 0 outside any split.

SplitN

Total sibling count of the last Split / Repeat (split.n). 1 outside any split.

Depth

Current derivation depth (depth); the root rule runs at 0.

Named(String)

A named binding: rule parameter, grammar attribute, or constant — resolved in that order at evaluation time.
