Struct ElementaryProperties 

pub struct ElementaryProperties {
    pub derivative_rule: Option<DerivativeRule>,
    pub antiderivative_rule: Option<AntiderivativeRule>,
    pub special_values: Vec<SpecialValue>,

}

Elementary function properties (sin, cos, exp, log)

Performance-optimized layout with hot path data first for cache-friendly access patterns.

Note: Evaluation is handled by direct dispatch through Expression::evaluate_function_dispatch() for performance. This struct stores only mathematical properties, not evaluation logic.

Fields

derivative_rule: Option<DerivativeRule>

Most frequently accessed property (hot path data)

antiderivative_rule: Option<AntiderivativeRule>

Antiderivative rule for integration

special_values: Vec<SpecialValue>

Special values for exact computation Examples: sin(0) = 0, cos(π/2) = 0, exp(0) = 1

identities: Box<Vec<MathIdentity>>

Mathematical identities (boxed to keep struct small) Examples: sin²(x) + cos²(x) = 1, e^(ln(x)) = x

domain_range: Box<DomainRangeData>

Domain and range information (cold path data)

periodicity: Option<Expression>

Periodicity information (if applicable)

wolfram_name: Option<&'static str>

Wolfram Language function name Used for Wolfram formatting without hardcoded matches Example: “sin” → “Sin”, “ln” → “Log”
