Enum UnaryMathFunction 

#[non_exhaustive]
pub enum UnaryMathFunction {
    Sin,
    Sqrt,
    Cos,
    Exp,
    Log,
    Conj,
    Real,
    Imag,
    Abs,
    Abs2,
    Arg,
}
Description

Dimension-aware unary mathematical function.

Kept separate from ExprNode so that adding a function does not need a new node variant. Whole-model validation checks each function’s dimensional rules.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Sin

Sine of a dimensionless scalar.

§

Sqrt

Real nonnegative or principal complex square root; halves dimensions.

§

Cos

Cosine of a dimensionless scalar.

§

Exp

Exponential of a dimensionless scalar.

§

Log

Natural logarithm, with the principal branch for complex input.

§

Conj

Complex conjugate, preserving dimension and scalar domain.

§

Real

Explicit real component, preserving dimension.

§

Imag

Explicit imaginary component, preserving dimension.

§

Abs

Real magnitude, preserving dimension.

§

Abs2

Squared real magnitude, squaring dimension.

§

Arg

Principal dimensionless phase; zero amplitude is undefined.

Implementations§

impl UnaryMathFunction

Signature links:§UnaryMathFunction

pub fn evaluate(self, value: &ValueLiteral) -> Result<ValueLiteral, Diagnostic>

Signature links:evaluateValueLiteralResultValueLiteralDiagnostic

Evaluate one finite typed scalar with the canonical domain and branch rules. Real roots/logarithms never promote invalid real inputs to complex values. Complex roots/logarithms use the principal branch; zero phase is rejected.
