Variants

Add

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

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

Down

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

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

Up

The pointer has stopped making contact with the device.

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

Remove

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

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

Implementations

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 Decodable for PointerEventPhase

fn new_empty() -> Self

Creates a new value of this type with an “empty” representation.

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

Decodes an object of this type from the decoder’s buffers into self. Callers must ensure that offset is a multiple of Layout::inline_align, and that decoder.buf has room for reading Layout::inline_size bytes at offset.

impl Encodable for PointerEventPhase

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

Encode the object into the buffer. Any handles stored in the object are swapped for Handle::INVALID. Callers must ensure that offset is a multiple of Layout::inline_align, and that encoder.buf has room for writing Layout::inline_size bytes at offset.

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 Layout for PointerEventPhase

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 the type’s alignment. Must be a multiple of inline_align.

fn supports_simple_copy() -> boolwhere Self: Sized,

Returns true iff the type can be encoded or decoded via simple copy.

impl Ord for PointerEventPhase

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<PointerEventPhase> for PointerEventPhase

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<PointerEventPhase> 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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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