Enum Exactness 

#[non_exhaustive]
pub enum Exactness {
    Defined,
    Measured,
}

Whether a factor is exact by definition or a measured value (ADR-002).

Variants (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.

Defined

Exact by definition (SI definition, statute, treaty or convention).

Measured

A measured value, stored as the exact rational of the published decimal.

Implementations

impl Exactness

pub const fn name(self) -> &'static str

The stable lower-case name used in data files and JSON output.

pub fn from_name(name: &str) -> Option<Self>

Reads a name produced by Exactness::name.

pub const fn combine(self, other: Self) -> Self

The weaker of two flags: Measured if either is measured.
