}

A unit as it appears in a compiled data table (plain data, const-constructible).

Fractions are (numerator, denominator) pairs; the registry validates and reduces them when loading.

Fields

symbol: &'static str

Primary symbol, for example psi.

aliases: &'static [&'static str]

Alternative symbols, for example ["\u{b0}C"] for degC.

dim: [i8; 7]

Dimension exponents of [kg, m, s, A, K, mol, cd].

kind: Kind

Quantity kind.

shape: Shape

Conversion shape to the coherent SI unit.

factor: (i128, i128)

Factor a in si = a * x + b, as (numerator, denominator).

offset: (i128, i128)

Offset b in si = a * x + b, as (numerator, denominator).

exactness: Exactness

Defined or measured.

prefixes: PrefixMode

Accepted prefixes.

namespace: &'static str

Namespace, si or std for the core table.

source: &'static str

Citation of the primary definition.

note: &'static str

Free-text note (derivation, caveats).
