Enum ImageError 

pub enum ImageError {
    Decode,
    Encode,
    Unsupported,
    Gone,
}

Why an image operation could not answer.

Variants

Decode

The bytes are not an image this platform decodes.

Encode

The image decoded, but this backend cannot encode the format asked for. encode_formats says which it can.

Unsupported

The backend has no path for this at all (probe Cap::ImageDecode / Cap::ImageEncode).

Gone

The id named no live image: released already, or never decoded.

Trait Implementations

impl Clone for ImageError

fn clone(&self) -> ImageError

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Copy for ImageError

impl Debug for ImageError

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

Formats the value using the given formatter.

impl Display for ImageError

impl Eq for ImageError

impl Error for ImageError

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 ImageError

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

Equality operator ==.

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

Inequality operator !=.
