A person's nationality, named by the country, as ISO 3166-1 codes it: GB. Personal data.

People and contact; not ordered; since Jadpo 0.1.0.

Make one

Pick one of its variants, Nationality.ad.

text.parse(raw, as: Nationality) reads one from its text; text that isn't one at all fails malformed, such as GBR, British or UK.

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
FR "FR"
GB "GB"

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

Shown to people

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

With locale: Locale.en_gb:

Value Shown
FR France
GB United Kingdom

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.
