Enum Exactness 

pub enum Exactness {
    Exact,
    Rounded,
    Approximate,
}

How exact a result is. These classifications are mutually exclusive and are never inferred from mere repeatability.

Variants

Exact

The result is mathematically exact under the selected representation.

Rounded

The result was rounded under a declared context (e.g. decimal division, money quantization). The context and inexactness are reported.

Approximate

The result is a floating-point approximation. Accuracy is bounded by the method, not by the representation alone.

Implementations

impl Exactness

pub fn as_str(self) -> &'static str

pub fn combine(self, other: Exactness) -> Exactness
