Struct RuleDef 

pub struct RuleDef {
    pub params: Vec<String>,
    pub variants: Vec<RuleVariant>,
}

The CGA Shape Grammar derivation engine.

Rules are registered by name, then derive is called with a root scope and root rule name. The engine expands rules breadth-first until every branch terminates with an I(mesh) terminal.

Stochastic rules with multiple weighted variants use the engine’s seed for reproducible randomness — the same seed always yields the same building. A registered rule: declared parameter names plus its weighted variants.

Fields

params: Vec<String>

Parameter names bound to call-argument values at invocation. Empty for parameterless rules.

variants: Vec<RuleVariant>
