ContentRating

An age rating by the body that gave it, written BBFC 12A: rating is one of scheme's categories.

Media and visual; not ordered; since Jadpo 0.1.0.

Make one

Build one from its fields, ContentRating { scheme: ... rating: ... }.

text.parse(raw, as: ContentRating) reads one from its text; text that isn't one at all fails malformed, such as BBFC PG-13, PEGI 15 or MPAA R.

Its parts keep these rules; a value that breaks one fails with the rule's name:

• rating_of_scheme: rating is one of its scheme's categories

Fields

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 2 columns, each named for the field, _ and its suffix. This is PEGI 16:

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.
