Enum Context 

pub enum Context {
    View(ViewRef),
}

The region from which injection is attempted for injected events. As the context, it serves two purposes: (1) Scoping. It confirms the |Device|’s authority to inject pointer events on the specified target. Specifically, the context must be a view-tree ancestor of the target. (2) Coordinate System. It provides the reference coordinate system to define the viewport’s position and size, relative to the target.

Trait Implementations

impl Debug for Context

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

Formats the value using the given formatter.

impl<___E> Encode<Context, ___E> for Context

where ___E: InternalHandleEncoder + ?Sized + HandleEncoder,

fn encode( self, encoder: &mut ___E, out: &mut MaybeUninit<Context>, _: (), ) -> Result<(), EncodeError>

Encodes this value into an encoder and output.

const COPY_OPTIMIZATION: CopyOptimization<Self, W> = _

Whether the conversion from Self to W is equivalent to copying the raw bytes of Self.

impl<___E> EncodeOption<Context, ___E> for Context

where ___E: ?Sized, Context: Encode<Context, ___E>,

fn encode_option( this: Option<Self>, encoder: &mut ___E, out: &mut MaybeUninit<Context>, _: (), ) -> Result<(), EncodeError>

Encodes this optional value into an encoder and output.

impl FromWire<Context> for Context

fn from_wire(wire: Context) -> Self

Converts the given owned value to this type.

const COPY_OPTIMIZATION: CopyOptimization<W, Self> = _

Whether the conversion from W to Self is equivalent to copying the raw bytes of W.

impl FromWireOption<Context> for Box<Context>

fn from_wire_option(wire: Context) -> Option<Self>

Converts the given owned value to an option of this type.

impl FromWireOption<Context> for Context

fn from_wire_option(wire: Context) -> Option<Self>

Converts the given owned value to an option of this type.

impl PartialEq for Context

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