VatNumber

A VAT registration number, written as VIES writes it: its country's code (EL for Greece) and the number in that country's form, GB980780684.

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

Make one

Build one from its fields, VatNumber { country: ... number: ... }.

text.parse(raw, as: VatNumber) reads one from its text; text that isn't one at all fails malformed, such as GB802311781, DE143454215 or FR84323140391.

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

• number_of_country: number is in the form of its country's numbers

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 IE6388047V:

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.
