Enum KeyboardType 

pub enum KeyboardType {
    Text,
    Multiline,
    Number,
    Decimal,
    Phone,
    Email,
    Url,
    Password,
    VisiblePassword,
    Name,
    StreetAddress,
    DateTime,
    None,
}

Which keys the software keyboard should offer.

The platform decides what that means: a phone keypad on Android and iOS, and nothing at all on a desktop, which has one keyboard and it is already open.

Variants

Text

Ordinary text, with suggestions and composition. The default.

Multiline

Text over several lines, where the action key is a newline.

Number

Whole numbers.

Decimal

Numbers with a decimal separator and a sign.

Phone

A telephone keypad: digits, +, *, #.

Email

An email address: an @ and a . within reach, and no auto-capitalisation.

Url

A URL: a / and a .com within reach.

Password

A secret. The keyboard neither learns it nor suggests it, which is the whole point and is not something the masking dots can do on their own.

VisiblePassword

A secret the field shows in the clear — a one-time code, a generated passphrase being checked. Still never learned.

Name

A person’s name: each word capitalised, no sentence casing.

StreetAddress

A postal address.

DateTime

A date or a time.

None

No software keyboard: the field is edited some other way — a picker, a scanner, a hardware keyboard only.

Implementations

impl KeyboardType

pub const fn android_input_type(self) -> i32

The Android InputType bit field for this keyboard.

None is TYPE_NULL, which is zero — the value that tells Android there is nothing to type into. It is also what the bridge produced for every field before it had an InputType at all, which is why a keyboard used to arrive with no composition, no swipe and no CJK.

pub const fn is_secret(self) -> bool

Whether the keyboard must never learn what is typed into it.

Android infers this from the variation bits, so nothing else has to be sent — but the question is worth asking in this vocabulary too, because it is the reason Password exists as a type rather than as a way of drawing dots.
