What went wrong in a page-level operation that can actually fail.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

FunctionArity

A function was evaluated with a number of inputs its /Domain does not describe, or an output slice shorter than its /Range (ISO 32000-1 §7.10.1).

Fields

expected: usize

Inputs the function declares.

got: usize

Inputs the caller supplied.

outputs: usize

Outputs the function declares.

got_outputs: usize

Length of the caller’s output slice.

FunctionInterval

A function’s /Domain names an interval whose low bound exceeds its high bound, which PDFium refuses to evaluate against.

ImageBadDict

An image dictionary’s /Width, /Height or /BitsPerComponent is outside the range PDFium accepts.

Fields

what: &'static str

Which value was rejected.

ImageNoColorSpace

No colorspace could be resolved for a non-mask image, so its samples cannot be turned into pixels.

ImageUndecodable

The image’s sample data could not be produced: a filter with no decoder, a codec that rejected the stream, or a chain that decoded to fewer bytes than one scanline needs.

Fields

what: &'static str

Which stage gave up.

ImageTooLarge

The image is larger than Limits::max_image_bytes allows, or its pitch computation overflowed.

CodecRejected

A JBIG2 or JPEG 2000 codec rejected its input.

Fields

codec: &'static str

"JBIG2" or "JPX".

Unresolved(ObjRef)

An indirect object a page-level structure needed could not be fetched.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 Error

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

Equality operator ==.

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

Inequality operator !=.
