Struct RenderState 

pub struct RenderState<'a> { /* private fields */ }

Mutable state for one render operation.

RuleSet::render_rule creates a fresh state for each call. The state tracks per-render bindings, the rule call stack used for cycle detection, and the random number generator used by choice nodes.
