Lei

A Legal Entity Identifier (ISO 17442), its mod-97 check digits passing: 506700GE1G29325QX363.

Money and banking; not ordered; since Jadpo 0.1.0.

Make one

Build one from its text, Lei("506700GE1G29325QX363"), which checks it: text that isn't one breaks format.

text.parse(raw, as: Lei) reads one from its text; text that isn't one at all fails malformed, such as 506700GE1G29325QX364, 506700ge1g29325qx363 or 506700GE1G29325QX3.

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. HWUPKR0MPOU8FGXBT394 is stored as 'HWUPKR0MPOU8FGXBT394'.

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.
