Struct SymmetryChecker 

pub struct SymmetryChecker {
    pub even: bool,
    pub tolerance: f64,
}

Validates even or odd function symmetry: f(−x) == f(x) (even) or f(−x) == −f(x) (odd).

Only positive inputs need be passed; the checker evaluates both x and −x internally.

Fields

even: bool

true → even symmetry f(−x) == f(x); false → odd symmetry f(−x) == −f(x).

tolerance: f64

Absolute tolerance for the symmetry assertion.

Implementations

impl SymmetryChecker

pub fn new_even(tolerance: f64) -> Self

Build a checker for even-symmetric functions.

pub fn new_odd(tolerance: f64) -> Self

Build a checker for odd-symmetric functions.

pub fn check(&self, f: &dyn Fn(f64) -> f64, inputs: &[f64]) -> bool

Returns true when f satisfies the configured symmetry at every input in inputs.

inputs may contain positive, negative, or zero values. For each x the checker evaluates both f(x) and f(−x).

pub fn check_with_first_violation( &self, f: &dyn Fn(f64) -> f64, inputs: &[f64], ) -> (bool, Option<usize>)

Like Self::check but returns the index of the first violation.

Trait Implementations

impl Clone for SymmetryChecker

fn clone(&self) -> SymmetryChecker

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SymmetryChecker

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
