Enum DecodeError 

pub enum DecodeError {
    NoDecoder,
    Unsupported(Vec<Declined>),
    InvalidData(String),
    LimitExceeded(&'static str),
    Failed(String),
    Image(ImageError),
    Closed,
}

DecodeError is why a decode did not produce an image.

Variants

NoDecoder

NoDecoder means the loader was built with no decoders at all.

Unsupported(Vec<Declined>)

Unsupported means every decoder declined the bytes; each entry says why.

InvalidData(String)

InvalidData means a decoder recognised the format and found the bytes damaged.

LimitExceeded(&'static str)

LimitExceeded means a DecodeLimits bound was hit; the text names which one.

Failed(String)

Failed means a decoder or the platform failed without proving the bytes invalid — an allocation failure, a system API declining.

Image(ImageError)

Image means the decoded frame could not become an image on this device.

Closed

Closed means the loader was dropped before the work ran.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Eq for DecodeError

impl Error for DecodeError

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<DecodeError> for OpenError

fn from(error: DecodeError) -> Self

Converts to this type from the input type.

impl From<ImageError> for DecodeError

fn from(error: ImageError) -> Self

Converts to this type from the input type.

impl PartialEq for DecodeError

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

Equality operator ==.

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

Inequality operator !=.
