Errors returned by scale kernel operations.

Variants

BufferSizeMismatch

Source or destination buffer has incorrect length.

Fields

expected: usize

actual: usize

InvalidDimensions

Image dimensions are zero or invalid.

Fields

width: u32

height: u32

PixelCountOverflow

Pixel count would overflow.

PlanarMismatch

Planar planes are inconsistent in length.

Fields

plane: &'static str

expected: usize

actual: usize

Trait Implementations

impl Clone for ScaleError

fn clone(&self) -> ScaleError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScaleError

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

Formats the value using the given formatter.

impl Display for ScaleError

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

Formats the value using the given formatter.

impl Error for ScaleError

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 ScaleError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
