HttpStatus

On this page

An HTTP response's status code, from 100 to 599.

Use it for what a response carried, such as in a log. In a route, return your failures, and let Jadpo pick the status.

Shape

One whole number from 100 to 599.

Example

example
HttpStatus(404)

HttpStatus(number) checks the number, and one outside its limits breaks min or max.

text.parse(raw, as: HttpStatus) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as 99, 600 or 0200.

Good to know

  • == tells you whether two are the same, and < and list.sort_by compare and sort them.

In JSON

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

json
200404599

Details

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

HttpStatus is in the group Web and network, 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: 200, 404 and 599.

How it is stored

It is stored in one column named for the field, of type integer. 404 is stored as 404.

How it is shown to people

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

With locale: Locale.en_gb:

Value Shown
200 200
404 404
599 599

Operations

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