Available on crate feature iosurface only.

Re-exports the Metal framework surface for this item. Errors returned while creating an IOSurface-backed texture.

Variants

InvalidPlane

The requested plane does not exist for this surface.

Fields

plane_index: usize

UnsupportedPixelFormat

The surface format and plane do not map to a supported Metal format.

Fields

fourcc: u32

plane_index: usize

EmptyPlane

The selected plane has zero dimensions or row stride.

Fields

plane_index: usize

width: usize

height: usize

bytes_per_row: usize

IncompatiblePlaneLayout

The plane row stride cannot contain its selected Metal format.

Fields

plane_index: usize

bytes_per_row: usize

minimum_bytes_per_row: usize

IntegerOutOfRange

Plane metadata cannot be represented by the native bridge.

Fields

field: &'static str

value: usize

NativeCreationFailed

Metal rejected the validated IOSurface texture descriptor.

Trait Implementations

impl Clone for IOSurfaceMetalError

fn clone(&self) -> IOSurfaceMetalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IOSurfaceMetalError

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

Formats the value using the given formatter.

impl Display for IOSurfaceMetalError

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

impl Eq for IOSurfaceMetalError

impl Error for IOSurfaceMetalError

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

Returns 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 PartialEq for IOSurfaceMetalError

fn eq(&self, other: &IOSurfaceMetalError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
