pub struct AnySurface(/* private fields */);
Expand description

A Arc of a HalSurface<A>, for any backend A.

Any AnySurface is just like an Arc<HalSurface<A>>, except that the A type parameter is erased. To access the Surface, you must downcast to a particular backend with the [downcast_ref] or [take] methods.

Implementations§

source§

impl AnySurface

source

pub fn new<A: HalApi>(surface: HalSurface<A>) -> AnySurface

Return an AnySurface that holds an owning Arc to HalSurface.

source

pub fn backend(&self) -> Backend

source

pub fn downcast_ref<A: HalApi>(&self) -> Option<&HalSurface<A>>

If self is an Arc<HalSurface<A>>, return a reference to the HalSurface.

source

pub fn take<A: HalApi>(self) -> Option<Arc<HalSurface<A>>>

If self is an Arc<HalSurface<A>>, returns that.
