Errors that can occur during PDF parsing and object resolution.

Marked #[non_exhaustive] so new error variants can land additively; downstream consumers must include a wildcard arm in match sites.

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.

NotAPdf

UnsupportedVersion(String)

NoStartXref

MalformedXref(usize)

MalformedTrailer

ObjectNotFound

Fields

obj_num: u32

gen_num: u16

UnexpectedToken

Fields

expected: String

got: String

Unterminated(&'static str)

InvalidObject(usize)

StreamMissingLength

UnsupportedFilter(String)

DecompressionError(String)

MissingKey(&'static str)

TypeMismatch

Fields

key: String

expected: &'static str

PageOutOfRange(usize, usize)

CircularReference(u32, u16)

NestingTooDeep

A recursive-descent parse hit its nesting cap.

Raised instead of letting a crafted file exhaust the native stack, which aborts the process rather than unwinding.

Fields

context: &'static str

What was being parsed, e.g. "array/dictionary".

limit: u32

The cap that was reached.

PasswordRequired

Other(String)

Trait Implementations

impl Debug for PdfError

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

Formats the value using the given formatter.

impl Display for PdfError

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

Formats the value using the given formatter.

impl Error for PdfError

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.
