Struct GraphicsResource 

pub struct GraphicsResource { /* private fields */ }

A CUDA-side handle to a graphics-API resource. Drops unregister the resource via cuGraphicsUnregisterResource.

Implementations

impl GraphicsResource

pub unsafe fn from_raw(context: &Context, handle: CUgraphicsResource) -> Self

Wrap a raw CUgraphicsResource. The resource is assumed to be registered already (e.g. from cu<API>Register*).

Safety

handle must be a live, registered resource. baracuda unregisters it when this wrapper (and all clones) drop.

pub fn as_raw(&self) -> CUgraphicsResource

pub fn set_map_flags(&self, flags: u32) -> Result<()>

Change the map flags before mapping (e.g. READ_ONLY for shader sampling, WRITE_DISCARD for compute output).

pub fn map(&self, stream: &Stream) -> Result<()>

Map the resource on stream so CUDA can access it. Pair with Self::unmap.

pub fn unmap(&self, stream: &Stream) -> Result<()>

Unmap the resource on stream, releasing it back to the graphics API.

pub fn mapped_pointer(&self) -> Result<(CUdeviceptr, usize)>

Retrieve the device pointer + size for a mapped buffer-type resource (typical of GL buffer objects, D3D buffers).

pub fn mapped_array(&self, array_index: u32, mip_level: u32) -> Result<CUarray>

Retrieve the subresource CUDA array for a mapped image / texture resource (GL textures, D3D textures, VDPAU surfaces).

pub fn mapped_mipmapped_array(&self) -> Result<CUmipmappedArray>

Retrieve the mipmapped-array handle for a mapped mipmapped texture.

pub fn map_all(resources: &[Self], stream: &Stream) -> Result<()>

Bulk-map multiple resources in one call. More efficient than calling Self::map per resource.

pub fn unmap_all(resources: &[Self], stream: &Stream) -> Result<()>

Bulk-unmap.

Trait Implementations

impl Clone for GraphicsResource

fn clone(&self) -> GraphicsResource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphicsResource

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