Struct BoundaryChecker 

pub struct BoundaryChecker {
    pub name: String,
}

Validates function values at domain boundaries.

Useful for CDFs (F(−∞) == 0, F(+∞) == 1), PDFs (f(0) == 0 for half-bounded domains), and similar mathematical requirements.

Fields

name: String

Display name used in error messages.

Implementations

impl BoundaryChecker

pub fn new(name: impl Into<String>) -> Self

Create a new BoundaryChecker with the given display name.

pub fn check_bounds( &self, f: &dyn Fn(f64) -> f64, lower: f64, upper: f64, expected_lower: f64, expected_upper: f64, tolerance: f64, ) -> (bool, bool)

Check that f(lower) matches expected_lower and f(upper) matches expected_upper within tolerance.

Returns (lower_ok, upper_ok).

pub fn check_point( &self, f: &dyn Fn(f64) -> f64, point: f64, expected: f64, tolerance: f64, ) -> bool

Check a single boundary point.

pub fn check_multiple( &self, f: &dyn Fn(f64) -> f64, points: &[(f64, f64)], tolerance: f64, ) -> usize

Check a collection of (point, expected) pairs. Returns the number of points that satisfied the tolerance.
