What a field is for: what an autofill service should put in it, and what it should learn from it when the form is submitted.

The catalogue is the useful part of the platform’s, not all of it: what a sign-in, a sign-up, an address and a card payment need. A hint the list does not carry is a hint to add here, with its platform name and a test.

Variants

Username

The account’s name — an email address often plays this part as well.

NewUsername

A username being created, so that the service offers to save it rather than to fill it.

Password

An existing password, to be filled.

NewPassword

A password being created: never filled from what is saved, and offered for saving once the form is submitted.

OneTimeCode

A one-time code, usually arriving by SMS. The platform offers it above the keyboard, which is what saves the reader leaving the application to go and read it.

Email

An email address.

Name

A person’s whole name.

GivenName

The given (first) name alone.

FamilyName

The family (last) name alone.

TelephoneNumber

A telephone number.

StreetAddress

The street part of an address — the lines above the town.

PostalAddress

A whole postal address in one field.

PostalCode

The postal code.

AddressCity

The town or city.

AddressState

The state, region or county.

CountryName

The country.

CreditCardNumber

A payment card’s number.

CreditCardExpirationDate

Its expiry date, as one field.

CreditCardSecurityCode

Its security code (CVC).

Implementations

impl AutofillHint

pub const fn android(self) -> &'static str

The string Android’s autofill services expect for this hint.

Several are not what the hint is called: personName, emailAddress, phoneNumber, addressLocality for a town, addressRegion for a state, addressCountry for a country, smsOTPCode for a one-time code.

pub const fn is_secret(self) -> bool

Is what this field holds a secret, so that it must never be shown in a screenshot of the structure, nor learned by a keyboard?

The field’s KeyboardType already stops the keyboard learning it; this is the same question asked of the hint, for the paths that only ever see one — reporting a value to the autofill service, above all.
