ClothingSize

On this page

A clothing size in its system, as the label writes it: UK 10, US M.

Use it for clothes in a shop. For shoes, use ShoeSize.

Shape

Field Type Required?
system ClothingSizeSystem Yes
size Text Yes

Example

example
ClothingSize { system: ClothingSizeSystem.uk size: "10" }

text.parse(raw, as: ClothingSize) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as UK10, UK 10 or UK m.

Good to know

  • Two sizes in different systems aren't compared or converted. UK 10 and EU 38 are simply different values.
  • == tells you whether two are the same. < and list.sort_by don't take it, so sort by one of its parts instead.

In JSON

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

json
"UK 10""EU 38""US 00"

Details

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

ClothingSize 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: UK 10, EU 38 and US 00.

How it is stored

It is stored in 2 columns, each named for the field, _ and its suffix. This is US 00:

Column Type Holds
<field>_system text 'US'
<field>_size text '00'

How it is shown to people

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

With locale: Locale.en_gb:

Value Shown
UK 10 UK 10
EU 38 EU 38
US 00 US 00
US M US M
UK 3XL UK 3XL

Operations

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