Struct ViewImageHandle 

pub struct ViewImageHandle(/* private fields */);

Handle to an image loading or loaded in the View Process.

The image is disposed when all clones of the handle are dropped.

Implementations

impl ViewImageHandle

pub fn dummy() -> Self

New handle to nothing.

pub fn is_dummy(&self) -> bool

Is handle to nothing.

pub fn image_id(&self) -> ImageId

Image ID.

Is ImageId::INVALID for dummy.

pub fn app_id(&self) -> Option<AppId>

Application that requested this image.

Images can only be used in the same app.

Is None for dummy.

pub fn view_process_gen(&self) -> ViewProcessGen

View-process generation that provided this image.

Images can only be used in the same view-process instance.

Is ViewProcessGen::INVALID for dummy.

pub fn downgrade(&self) -> WeakViewImageHandle

Create a weak reference to this handle.

Trait Implementations

impl Clone for ViewImageHandle

fn clone(&self) -> ViewImageHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ViewImageHandle

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

Formats the value using the given formatter.

impl Drop for ViewImageHandle

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq for ViewImageHandle

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