Struct RenderHandle 

pub struct RenderHandle<T>(/* private fields */);

Typed access to a concrete render object’s class-specific state.

get / get_mut are point access: drop the borrow before any call that can re-enter this slot.

Implementations

impl<T: RenderBox> RenderHandle<T>

pub fn new_box(app: &mut App, object: T) -> RenderHandle<T>

Creates a box-protocol render object in app.

impl<T: 'static> RenderHandle<T>

pub fn get(self, app: &App) -> &T

The concrete state. Drop the borrow before a virtual call.

pub fn get_mut(self, app: &mut App) -> &mut T

See get.

pub fn handle(self) -> Handle<T>

The foundation handle, for a inset_foundation::Listener::handle_method tear-off.

pub fn from_handle(handle: Handle<T>) -> RenderHandle<T>

The render handle for a foundation handle, which is what such a tear-off is called with.

impl<T: RenderSliver> RenderHandle<T>

pub fn new_sliver(app: &mut App, object: T) -> RenderHandle<T>

Creates a sliver-protocol render object in app.

Trait Implementations

impl<T> Clone for RenderHandle<T>

fn clone(&self) -> RenderHandle<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Copy for RenderHandle<T>

impl<T> Debug for RenderHandle<T>

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

Formats the value using the given formatter.

impl<T> Eq for RenderHandle<T>

impl<T> Hash for RenderHandle<T>

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 HitTestTarget for RenderHandle<RenderView>

Flutter’s RenderObject.handleEvent default: the view itself does nothing with events.

fn handle_event( &self, _app: &mut App, _event: &PointerEvent, _entry: &HitTestEntry, )

Override this method to receive events.

fn retained_handle(&self) -> Option<HandleId>

The arena object this target delivers to, if it is one, so a result kept across turns can retain it: Dart keeps the object alive by holding it in the path.

impl<T> PartialEq for RenderHandle<T>

fn eq(&self, other: &RenderHandle<T>) -> bool

Equality operator ==.

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

Inequality operator !=.

impl<T> Receiver for RenderHandle<T>

type Target = T

🔬This is a nightly-only experimental API. (arbitrary_self_types)

The target type on which the method may be called.
