Email

On this page

An email address, checked as one.

Use it for any address you send to or sign someone in with. To keep the name shown beside the address, use EmailWithName. Either is personal data with no personal: on the field: it counts as PersonalData.contact.

Shape

One value, with no fields to fill in. As text it reads someone@example.com.

Example

example
Email("mary@example.com")

text.parse(raw, as: Email) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as someone, someone@ or @example.com.

Good to know

  • Checking the form doesn't show that a mailbox exists. To find out, send a message to it.
  • == tells you whether two are the same. < and list.sort_by don't take it.
  • A field that holds one counts as personal data (contact), so you don't mark it yourself.

In JSON

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

json
"someone@example.com"

Details

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

Email is in the group People and contact, 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: someone@example.com.

How it is stored

It is stored in one column named for the field, of type text. someone@example.com is stored as 'someone@example.com'.

How it is shown to people

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

With locale: Locale.en_gb:

Value Shown
someone@example.com someone@example.com

Operations

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