Struct Surface 

pub struct Surface<D: SurfaceMemoryDescriptor> { /* private fields */ }

An owned VA surface that is tied to a particular Display.

Implementations

impl<D: SurfaceMemoryDescriptor> Surface<D>

pub fn display(&self) -> &Arc<Display>

pub fn sync(&self) -> Result<(), VaError>

Wrapper around vaSyncSurface that blocks until all pending operations on the render target have been completed.

Upon return it is safe to use the render target for a different picture.

pub fn as_id_vec(surfaces: &[Self]) -> Vec<VASurfaceID>

Convenience function to return a VASurfaceID vector. Useful to interface with the C API where a surface array might be needed.

pub fn query_status(&self) -> Result<Type, VaError>

Wrapper over vaQuerySurfaceStatus to find out any pending ops on the render target.

pub fn query_error(&self) -> Result<Vec<SurfaceDecodeMBError>, VaError>

pub fn id(&self) -> VASurfaceID

Returns the ID of this surface.

pub fn size(&self) -> (u32, u32)

Returns the dimensions of this surface.

pub fn export_prime(&self) -> Result<DrmPrimeSurfaceDescriptor, VaError>

Returns a PRIME descriptor for this surface.

Trait Implementations

impl<D: SurfaceMemoryDescriptor> AsMut<D> for Surface<D>

fn as_mut(&mut self) -> &mut D

Converts this type into a mutable reference of the (usually inferred) input type.

impl<D: SurfaceMemoryDescriptor> AsRef<D> for Surface<D>

fn as_ref(&self) -> &D

Converts this type into a shared reference of the (usually inferred) input type.

impl<D: SurfaceMemoryDescriptor> Drop for Surface<D>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
