Jb2(Jb2Error)

A JB2 bitonal image decoding error (stub).

Iw44(Iw44Error)

An IW44 wavelet image decoding error (stub).

Bzz(BzzError)

A BZZ compression decoding error.

PageNotFound(usize)

A page number was not found in the document.

InvalidStructure(&'static str)

The document structure is invalid or unexpected.

Unsupported(Cow<'static, str>)

A feature or format variant that is not yet supported.

Io(Error)

Trait Implementations

impl Debug for DjVuError

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

Formats the value using the given formatter.

impl Display for DjVuError

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

Formats the value using the given formatter.

impl Error for DjVuError

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.
