UN/CEFACT Recommendation No. 20 — Codes for Units of Measure Used in International Trade (Revision 17, 2021).

All data is generated at compile time from rec20.xlsx and embedded as static data. No runtime allocations, no I/O.

Example

use cefact_units::UnitOfMeasure;

let kg = UnitOfMeasure::from_code("KGM").unwrap();
assert_eq!(kg.name(), "kilogram");
assert_eq!(kg.symbol(), Some("kg"));
assert_eq!(kg.quantity(), Some("mass"));

let parsed: UnitOfMeasure = "MTR".parse().unwrap();
assert_eq!(parsed.to_string(), "MTR");

for unit in UnitOfMeasure::ALL {
    println!("{} — {}", unit.code(), unit.name());
}
