Enum KeyboardType

pub enum KeyboardType {
    Text,
    Number,
    Phone,
    Datetime,
    Multiline,
    // some variants omitted
}

Requests a specific keyboard type from the text editing subsystem.

This is most relevant for virtual keyboards which have some leeway in how the keyboard is presented to the user, as well as which input is acceptable.

For example, a NUMBER keyboard type may only allow decimal numbers to be entered. In addition, a virtual keyboard might only show a numeric keypad for text entry.

Variants

Text

Single-line text fields only. Use MULTILINE below for multiline text.

Number

A text field intended for entering numbers only.

Phone

A text field for entering phone numbers only (e.g. digits, limited punctuation, perhaps some validation).

Datetime

A text field for entering date and time. For example, may have a calendar widget on the side, to aid in date time entry.

Multiline

Multi-line text.

Trait Implementations

impl Clone for KeyboardType

fn clone(&self) -> KeyboardType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KeyboardType

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<D> Decode<KeyboardType, D> for KeyboardType

where D: ResourceDialect,

fn new_empty() -> KeyboardType

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl<D> Encode<KeyboardType, D> for KeyboardType

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl Hash for KeyboardType

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for KeyboardType

fn cmp(&self, other: &KeyboardType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for KeyboardType

fn eq(&self, other: &KeyboardType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for KeyboardType

fn partial_cmp(&self, other: &KeyboardType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TypeMarker for KeyboardType

type Owned = KeyboardType

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for KeyboardType

type Borrowed<'a> = KeyboardType

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<KeyboardType as TypeMarker>::Owned, ) -> <KeyboardType as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
