ContainerNumber

On this page

A shipping container's number, checked by its check digit: CSQU3054383.

Use it for sea and rail freight containers. For a parcel, use TrackingNumber. For a software container, use ContainerImage.

Shape

One value, held as text in one set form, with no parts: TOLU4734787.

Example

example
ContainerNumber("CSQU3054383")

ContainerNumber(raw) checks the text, and text that isn't one breaks the format rule.

text.parse(raw, as: ContainerNumber) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as CSQU3054384, CSQA3054383 or CSQU 305438 3.

Good to know

  • Write it with no spaces. text.format adds them: CSQU 305438 3.
  • == 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
"CSQU3054383""MSKU9070323""TOLU4734787"

Details

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

ContainerNumber is in the group Commerce and logistics, 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: CSQU3054383, MSKU9070323 and TOLU4734787.

How it is stored

It is stored in one column named for the field, of type text. MSKU9070323 is stored as 'MSKU9070323'.

How it is shown to people

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

With locale: Locale.en_gb:

Value Shown
CSQU3054383 CSQU 305438 3
MSKU9070323 MSKU 907032 3
TOLU4734787 TOLU 473478 7

Operations

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