Make one

Build one from its fields, TrackingNumber { carrier: ... number: ... }.

text.parse(raw, as: TrackingNumber) reads one from its text; text that isn't one at all fails malformed, such as upsn 1Z999AA10123456784, UPSN 1z999aa10123456784 or UPSN 1Z999AA10123456784.

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 FDXE 449044304137821:

Shown to people

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.
