Variants

Unimplemented(&'static str)

Lopdf does not (yet) implement a needed feature.

ObjectType

An Object has the wrong type, e.g. the Object is an Array where a Name would be expected.

Fields

expected: &'static str

found: &'static str

DictType

Fields

expected: &'static str

found: String

AlreadyEncrypted

PDF document is already encrypted.

CharacterEncoding

The encountered character encoding is invalid.

Decompress(DecompressError)

The stream couldn’t be decompressed.

Parse(ParseError)

Failed to parse input.

Decryption(DecryptionError)

Error when decrypting the contents of the file

DictKey(String)

Dictionary key was not found.

InvalidInlineImage(String)

Invalid inline image.

InvalidOutline(String)

Invalid document outline.

InvalidStream(String)

Invalid stream.

InvalidObjectStream(String)

Invalid object stream.

InvalidOffset(usize)

Byte offset in stream or file is invalid.

IO(Error)

IO error

NoOutline

PDF document has no outline.

NotEncrypted

PDF document is not encrypted.

MissingXrefEntry

Missing xref entry.

ObjectNotFound(ObjectId)

The Object ID was not found.

ReferenceCycle(ObjectId)

Dereferencing object failed due to a reference cycle.

PageNumberNotFound(u32)

Page number was not found in document.

NumericCast(String)

Numeric type cast failed.

ReferenceLimit

Dereferencing object reached the limit. This might indicate a reference loop.

TextStringDecode

Decoding text string failed.

Xref(XrefError)

Error while parsing cross reference table.

IndirectObject

Invalid indirect object while parsing at offset.

Fields

offset: usize

ObjectIdMismatch

Found object ID does not match expected object ID.

Syntax(String)

Syntax error while processing the content stream.

ToUnicodeCMap(UnicodeCMapError)

Could not parse ToUnicodeCMap.

TryFromInt(TryFromIntError)

UnsupportedSecurityHandler(Vec<u8>)

Encountered an unsupported security handler.

Trait Implementations

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 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 From<DecryptionError> for Error

fn from(source: DecryptionError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<TryFromIntError> for Error

fn from(source: TryFromIntError) -> Self

Converts to this type from the input type.
