Methods

impl UnsupportedError

pub fn from_format_and_kind(
    format: ImageFormatHint,
    kind: UnsupportedErrorKind
) -> Self

If the operation was not connected to a particular image format then the hint may be Unknown.

pub fn kind(&self) -> UnsupportedErrorKind

Returns the corresponding UnsupportedErrorKind of the error.

pub fn format_hint(&self) -> ImageFormatHint

Returns the image format associated with this error.

Trait Implementations

impl Debug for UnsupportedError

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

Formats the value using the given formatter.

impl Display for UnsupportedError

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

Formats the value using the given formatter.

impl Error for UnsupportedError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<ImageFormatHint> for UnsupportedError

fn from(hint: ImageFormatHint) -> Self

Performs the conversion.
