Details

A card scheme: visa, mastercard, american_express and so on.

Use it to show which logo goes beside a card, or to accept only certain schemes. money.mask tells it from a card's number, so you rarely set it yourself.

Shape

One of these 8 values:

CardBrand.american_express, CardBrand.diners_club, CardBrand.discover, CardBrand.jcb, CardBrand.maestro, CardBrand.mastercard, CardBrand.unionpay, CardBrand.visa.

Example

example

CardBrand.visa

text.parse(raw, as: CardBrand) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as americanexpress, Visa Electron or master_card.

Good to know

== tells you whether two are the same. < and list.sort_by don't take it.

In JSON

A string, in a request, a response or json.write:

json

"american_express""mastercard""visa"

Details

Text form, storage, how it is shown, and operations

CardBrand is in the group Money and banking, and has been in Jadpo since 0.1.0.

Text form

text.from writes one standard text form, the same form text.parse reads back: american_express, mastercard and visa.

How it is stored

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

How it is shown to people

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

With locale: Locale.en_gb:

Value	Shown
`american_express`	`American Express`
`mastercard`	`Mastercard`
`visa`	`Visa`

Operations

It also takes text.parse, text.from, text.format, json.read, json.write and ==. How every standard type behaves says how they work.
