Enum ImageEncodingError 

pub enum ImageEncodingError {
    EncodeFailed {
        kind: &'static str,
    },
    UnsupportedPixelFormat(PixelFormat),
    Backend(String),
}

Errors produced by crate::ImageEncoderPort.

Variants

EncodeFailed

The encoder failed for the given encoding kind.

Fields

kind: &'static str

Human-readable name of the encoding kind (e.g. "jpeg").

UnsupportedPixelFormat(PixelFormat)

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

Backend(String)

A backend-specific error surfaced as a string.

Trait Implementations

impl Debug for ImageEncodingError

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

Formats the value using the given formatter.

impl Display for ImageEncodingError

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

Formats the value using the given formatter.

impl Error for ImageEncodingError

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<ImageEncodingError> for OpenCvError

fn from(source: ImageEncodingError) -> OpenCvError

Converts to this type from the input type.
