Enum PointerEventPhase

#[repr(u32)]
pub enum PointerEventPhase {
    Add = 0,
    Hover = 1,
    Down = 2,
    Move = 3,
    Up = 4,
    Remove = 5,
    Cancel = 6,
}

Variants

Add = 0

The device has started tracking the pointer.

For example, the pointer might be hovering above the device, having not yet made contact with the surface of the device.

Hover = 1

The pointer has moved with respect to the device while not in contact with the device.

Down = 2

The pointer has made contact with the device.

For MOUSE devices, this is triggered when the primary button is pressed down to emulate a touch on the screen.

Move = 3

The pointer has moved with respect to the device while in contact with the device.

Up = 4

The pointer has stopped making contact with the device.

For MOUSE devices, this is triggered when the primary button is released.

Remove = 5

The device is no longer tracking the pointer.

For example, the pointer might have drifted out of the device’s hover detection range or might have been disconnected from the system entirely.

Cancel = 6

The input from the pointer is no longer directed towards this receiver.

Implementations

pub fn from_primitive(prim: u32) -> Option<Self>

pub const fn into_primitive(self) -> u32

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict enums should not use is_unknown

Trait Implementations

impl Clone for PointerEventPhase

fn clone(&self) -> PointerEventPhase

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PointerEventPhase

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<PointerEventPhase, D> for PointerEventPhase

fn new_empty() -> Self

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<()>

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

impl<D: ResourceDialect> Encode<PointerEventPhase, D> for PointerEventPhase

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

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

impl Hash for PointerEventPhase

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

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 PointerEventPhase

fn cmp(&self, other: &PointerEventPhase) -> 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 PointerEventPhase

fn eq(&self, other: &PointerEventPhase) -> 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 PointerEventPhase

fn partial_cmp(&self, other: &PointerEventPhase) -> 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 PointerEventPhase

type Owned = PointerEventPhase

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 PointerEventPhase

type Borrowed<'a> = PointerEventPhase

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: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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