Implementations

impl GpuResponse

pub fn encode( &self, flags: u32, fence_id: u64, ctx_id: u32, ring_idx: u8, resp: &mut Writer ) -> Result<u32, GpuResponseEncodeError>

Encodes a this GpuResponse into resp and the given set of metadata.

pub fn get_type(&self) -> u32

Gets the VIRTIO_GPU_* enum value that corresponds to this variant.

Trait Implementations

impl Debug for GpuResponse

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

Formats the value using the given formatter.

impl Display for GpuResponse

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

Formats the value using the given formatter.

impl Error for GpuResponse

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type based access to context intended for error reports.

impl From<GpuDisplayError> for GpuResponse

fn from(e: GpuDisplayError) -> GpuResponse

Converts to this type from the input type.

impl From<RutabagaError> for GpuResponse

fn from(e: RutabagaError) -> GpuResponse

Converts to this type from the input type.

impl From<Error> for GpuResponse

fn from(e: TubeError) -> GpuResponse

Converts to this type from the input type.

impl From<UdmabufError> for GpuResponse

fn from(e: UdmabufError) -> GpuResponse

Converts to this type from the input type.
