Struct RuleRegistry 

pub struct RuleRegistry { /* private fields */ }

A registry of differentiation rules, keyed by (lower-cased) function name.

Built-ins populate it; users extend it with RuleRegistry::register (design.md §3.2 — the “extensible rule registry” decision).

Implementations

impl RuleRegistry

pub fn new() -> Self

A registry populated with the built-in v1 rule set: + - * /, the unary chain rule for the trig / inverse-trig / exp / log / hyperbolic set plus abs, and power with a constant base or exponent (design.md §3.6).

pub fn register(&mut self, name: &str, rule: Rule)

Register (or override) a unary differentiation rule under name. The name is matched case-insensitively.
