Errors produced by crate::ImageOpsPort.

Variants

DimensionMismatch

Two inputs did not agree on (width, height, channels).

Fields

lhs: (u32, u32, u32)

Dimensions of the left-hand input as (width, height, channels).

rhs: (u32, u32, u32)

Dimensions of the right-hand input as (width, height, channels).

UnsupportedPixelFormat(PixelFormat)

The operation does not support the input’s pixel format.

UnsupportedConversion

The operation does not support the requested source/destination conversion.

Fields

src: PixelFormat

Source pixel format.

dst: PixelFormat

Destination pixel format.

InvalidParameter(&'static str)

A parameter was out of range or otherwise invalid.

EmptyInput

The input buffer was empty where a non-empty one was required.

Backend(String)

A backend-specific error surfaced as a string.

Trait Implementations

impl Debug for ImageOpsError

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

Formats the value using the given formatter.

impl Display for ImageOpsError

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

Formats the value using the given formatter.

impl Error for ImageOpsError

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<ImageOpsError> for OpenCvError

fn from(source: ImageOpsError) -> OpenCvError

Converts to this type from the input type.
