Enum PointerSource 

pub enum PointerSource {
    Mouse,
    Touch {
        finger_id: FingerId,
        force: Option<Force>,
    },
    TabletTool {
        kind: TabletToolKind,
        data: TabletToolData,
    },
    Unknown,
}

Represents the pointer type and its data for a pointer event.

Wayland/X11: Unknown device types are converted to known variants by the system.

Variants

Mouse

Touch

Represents a touch event.

Every time the user touches the screen, a WindowEvent::PointerEntered and a WindowEvent::PointerButton with ElementState::Pressed event with an unique identifier for the finger is emitted. When a finger is lifted, a WindowEvent::PointerButton with ElementState::Released and a WindowEvent::PointerLeft event is generated with the same FingerId.

After a WindowEvent::PointerEntered event has been emitted, there may be zero or more WindowEvent::PointerMoved events when the finger is moved or the touch pressure changes.

A WindowEvent::PointerLeft without a WindowEvent::PointerButton with ElementState::Released event is emitted when the system has canceled tracking this touch, such as when the window loses focus, or on mobile devices if the user moves the device against their face.

The FingerId may be reused by the system after a WindowEvent::PointerLeft event. The user should assume that a new WindowEvent::PointerEntered event received with the same ID has nothing to do with the old finger and is a new finger.

Platform-specific

macOS: Unsupported.

Fields

finger_id: FingerId

force: Option<Force>

Describes how hard the screen was pressed. May be None if the hardware does not support pressure sensitivity.

Platform-specific

• MacOS / Orbital / Wayland / X11: Always emits None.
• Android: Will never be None. If the device doesn’t support pressure sensitivity, force will either be 0.0 or 1.0. Also see the android documentation.
• Web: Will never be None. If the device doesn’t support pressure sensitivity, force will be 0.5 when a button is pressed or 0.0 otherwise.

TabletTool

Fields

kind: TabletToolKind

Describes as which tool kind the interaction happened.

data: TabletToolData

Describes how the tool was held and used.

Trait Implementations

impl Clone for PointerSource

fn clone(&self) -> PointerSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PointerSource

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

Formats the value using the given formatter.

impl From<PointerSource> for PointerKind

fn from(source: PointerSource) -> Self

Converts to this type from the input type.

impl PartialEq for PointerSource

fn eq(&self, other: &PointerSource) -> 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.
