Enum Error 

pub enum Error {
    Io(Error),
    AlreadyFilled(ObjRef),
    Unfilled(ObjRef),
    NestedStream,
    Unencodable {
        ch: char,

}

Any error raised while building or serializing a PDF.

Variants

Io(Error)

Underlying I/O failure while saving.

AlreadyFilled(ObjRef)

A reserved object was filled twice, or fill targeted a never-reserved reference.

Unfilled(ObjRef)

finish found a reserved object that was never filled.

NestedStream

A Stream object appeared nested inside another object; streams are only legal as indirect objects (ISO 32000 §7.3.8).

Unencodable

A character has no code in the target font’s encoding.

Fields

ch: char

The character that failed to encode.

font: &'static str

Base font name of the font that rejected it.

Image(String)

Image bytes could not be understood or are inconsistent.

EncryptedBase

A locked import source (encrypted, with no working decryptor) is refused: a copy would otherwise emit raw ciphertext into a plain output with no /Encrypt of its own. A password-opened encrypted source copies fine, since its content already reads as plaintext. An append base is refused whenever it carries an /Encrypt entry at all, password-opened or not: an appended update would need to encrypt its own new strings and streams too, which is not yet implemented.

MissingRoot

The base trailer names no /Root to build an update against.

MissingStartxref

The base file carries no startxref to chain an appended section’s /Prev to.

EmptyUpdate

An update section was asked for with no object set or put into it.

Other(String)

Anything else.

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
