Validation error returned when resource creation would fail.

Metal’s validation layer sometimes aborts the process instead of returning an error for certain invalid configurations. These safe wrapper methods validate parameters before calling Metal APIs and return this error type instead of allowing the process to abort.

Variants

MissingVertexFunction

Render pipeline descriptor is missing a required vertex function.

UnsupportedRasterSampleCount(UInteger)

The raster sample count is not supported by the device.

MissingComputeFunction

Compute pipeline descriptor is missing a required compute function.

InvalidTextureDimensions

Texture dimensions are invalid (width, height, or depth is zero).

Fields

width: UInteger

height: UInteger

depth: UInteger

InvalidMipmapCount

Requested mipmap count exceeds the maximum allowed for the texture dimensions.

Fields

requested: UInteger

max_allowed: UInteger

UnsupportedTextureSampleCount(UInteger)

The texture sample count is not supported by the device.

InvalidArrayLength

Array length is invalid (must be > 0 for array textures).

InvalidLodRange

LOD clamp range is invalid (min must be <= max).

Fields

min: f32

max: f32

InvalidAnisotropy(UInteger)

Max anisotropy value is invalid (must be >= 1 and power of 2).

InvalidHeapSize

Heap size is invalid (must be > 0).

CreationFailed(Option<Error>)

Metal failed to create the resource.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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 From<Error> for ValidationError

fn from(err: Error) -> Self

Converts to this type from the input type.
