Standard types

IdentityDocumentKind

On this page

What kind of identity document one is, written as its own name: passport, identity_card, driving_licence, residence_permit.

Tax and identity numbers; not ordered; since Jadpo 0.1.0.

Make one

Pick one of its variants, IdentityDocumentKind.passport.

text.parse(raw, as: IdentityDocumentKind) reads one from its text; text that isn't one at all fails malformed, such as passports, visa or id_card.

Variants

4 variants, each written as its own name: passport, identity_card, driving_licence, residence_permit.

Text, JSON and storage

text.from writes its canonical text, the one form text.parse reads back. JSON sends its canonical text as a string.

Text JSON
passport "passport"
driving_licence "driving_licence"

It is stored in one column named for the field, of type text. driving_licence is stored as 'driving_licence'.

Shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Value Shown
passport passport
driving_licence driving_licence

Operations

It has the contract's own operations: text.parse, text.from, text.format, json.read, json.write and ==. It isn't ordered, so < and sorting don't take it. Every standard type meets one contract says how they work.
