Make one

Pick one of its variants, Continent.africa.

text.parse(raw, as: Continent) reads one from its text; text that isn't one at all fails malformed, such as Europa, 150 or north_america.

Variants

6 variants, each written as its own name: africa, americas, antarctica, asia, europe, oceania.

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.

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

Shown to people

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

With locale: Locale.en_gb:

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.
