Enum Error 

pub enum Error {
    Source(SourceError),
    Syntax {
        offset: u64,
        message: &'static str,
    },
    UnexpectedEof,
    Limit(LimitKind),
    NoXref,
    NoRoot,
    MissingObject(ObjId),
    WrongType {
        expected: &'static str,
        found: &'static str,
    },
    Filter(&'static str),
    UnsupportedEncryption(String),
    InvalidPassword,
}

Everything that can go wrong in the syntax layer.

Variants

Source(SourceError)

The source failed to serve a read.

Syntax

Malformed syntax that could not be (or, in strict mode, was not allowed to be) repaired.

Fields

offset: u64

Byte offset in the file or in the buffer being parsed.

message: &'static str

What was expected or found.

UnexpectedEof

The input ended inside an object.

Limit(LimitKind)

A resource limit was exceeded.

NoXref

No xref and no objects could be found.

NoRoot

The trailer has no usable /Root.

MissingObject(ObjId)

An object is not in the xref, or cannot be found where it points.

WrongType

An object had a different type than required.

Fields

expected: &'static str

What was required.

found: &'static str

What was found.

Filter(&'static str)

A stream’s filters failed.

UnsupportedEncryption(String)

The file uses an encryption scheme this library cannot read.

InvalidPassword

Neither the user nor the owner password matched.

Implementations

impl Error

pub fn syntax(offset: u64, message: &'static str) -> Error

A syntax error at offset.

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<(), Error>

Formats the value using the given formatter.

impl Display for Error

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

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<SourceError> for Error

fn from(e: SourceError) -> Error

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Error
