codetics-evse-id

E-mobility identifiers in the IDRR / eMI³ / ISO 15118 format, without the COUNTRY*OPERATOR* prefix: a type character (E EVSE, P pool, S station) followed by up to 30 alphanumeric characters.

Generated identifiers end with a check character computed with the IDRR Annex 1 algorithm (Chen, Niemenmaa & Vinck, 2013). It detects every single-character error and every adjacent transposition. Annex 1 defines this check digit for contract IDs (EMAID); it is applied here to the local part of the identifier.

use codetics_evse_id::{EvseId, IdType, check_digit};

// Annex 1 worked example.
assert_eq!(check_digit("DE83DUIEN83QGZ").unwrap(), 'D');

let station = EvseId::station(1);
assert_eq!(station.as_str(), "S000001D");
let evse = EvseId::evse_of(&station, 2).unwrap();
assert_eq!(evse.kind(), IdType::Evse);
assert!(EvseId::parse(evse.as_str()).is_ok());
assert!(evse.with_operator("FR", "ABC").starts_with("FR*ABC*E"));
