Enum PdfReadError 

pub enum PdfReadError {
    NotAPdf,
    StartxrefNotFound,
    MalformedXref,
    MalformedTrailer,
    XrefStreamNotSupported,
    UnresolvableObject(u32),
    MalformedPageTree,
    Io(String),
}

Errors that can occur when reading a PDF file.

Variants

NotAPdf

The bytes do not start with a valid %PDF- header.

StartxrefNotFound

The startxref keyword or its offset could not be found.

MalformedXref

The cross-reference table is missing or could not be parsed.

MalformedTrailer

The trailer dictionary is missing or malformed.

XrefStreamNotSupported

The PDF uses a cross-reference stream (PDF 1.5+), which is not yet supported.

UnresolvableObject(u32)

An object reference could not be resolved (offset out of range or malformed).

MalformedPageTree

The page tree structure is invalid (missing /Count or /Pages).

Io(String)

An I/O error occurred while opening a file.

Trait Implementations

impl Debug for PdfReadError

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

Formats the value using the given formatter.

impl Display for PdfReadError

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

Formats the value using the given formatter.

impl Error for PdfReadError

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<Error> for PdfReadError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl PartialEq for PdfReadError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
