Struct StrictFinitePolicy

Source 
pub struct StrictFinitePolicy<ScalarType: Sized, const PRECISION: u32>(/* private fields */);
Expand description

A validation policy that checks for strict finiteness.

For floating-point types (ScalarType = f64, ScalarType = rug::Float), this policy ensures that the value is:

  • Not NaN (Not a Number).
  • Not positive or negative Infinity.
  • Not subnormal (for f64). While rug::Float maintains its specified precision rather than having distinct subnormal representation in the IEEE 754 sense, this policy will also reject rug::Float values that are classified as FpCategory::Subnormal (e.g., results of underflow that are tiny but not exactly zero).

For complex types (ScalarType = Complex<f64>, ScalarType = rug::Complex), this policy applies the strict finiteness check to both the real and imaginary parts.

This struct is a Zero-Sized Type (ZST) and uses PhantomData to associate with the ScalarType it validates.
