Struct GeomHandle 

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

Shared paint-time geometry. Canvas views use this on the UI thread; GPU callbacks hold it behind a mutex (Send + Sync).

Implementations

impl GeomHandle

pub fn new() -> Self

pub fn get(&self) -> FrameGeom

pub fn set(&self, g: FrameGeom)

pub fn arc(&self) -> Arc<Mutex<FrameGeom>>

Trait Implementations

impl Clone for GeomHandle

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for GeomHandle

fn default() -> Self

Returns the “default value” for a type.

impl From<Arc<Mutex<FrameGeom>>> for GeomHandle

fn from(arc: Arc<Mutex<FrameGeom>>) -> Self

Wrap GPU call sites that hold the raw mutex handle.

impl From<FrameGeom> for GeomHandle

fn from(g: FrameGeom) -> Self

Converts to this type from the input type.

impl From<Rc<Cell<FrameGeom>>> for GeomHandle

fn from(rc: Rc<Cell<FrameGeom>>) -> Self

Wrap canvas call sites holding the old cell handle by snapshotting the current value into the shared handle.
