Enum Error 

pub enum Error {
    EmptySurface,
    ColorSpace,
    BitmapContext,
    Surface(SurfaceError),
}

Failures from this backend.

Variants

EmptySurface

A surface was asked for with no pixels in it.

ColorSpace

CGColorSpaceCreateDeviceRGB returned null, which should not happen and leaves nothing sensible to fall back to.

BitmapContext

CGBitmapContextCreate failed, or produced a pitch that is not a whole number of 32-bit words.

Surface(SurfaceError)

A surface operation failed.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<SurfaceError> for Error

fn from(err: SurfaceError) -> Self

Converts to this type from the input type.
