Enum Error 

pub enum Error {
    Io(Error),
    Syntax {
        offset: usize,
        msg: String,
    },
    InvalidXref,
    ObjectNotFound(u32, u16),
    MissingKey(&'static str),
    TypeMismatch {
        expected: &'static str,
        found: &'static str,
    },
    UnsupportedFilter(String),
    Decode(String),
    Encrypted,
    PageNotFound(usize, usize),
    CircularReference(u32),
    Transport(String),
    RandomUnavailable(String),
    Other(String),
}

All errors surfaced by pdfboss.

Parsing is lenient by design; hard errors are reserved for unreadable cross-reference data (after recovery), encryption, and I/O.

Transport(String)

A transport-layer failure from an asynchronous byte source — an I/O error, an HTTP failure, a refused range request, a short read.

Carried as a rendered message so this crate stays free of transport types. Produced when a source whose own error type is richer (the asynchronous document’s) crosses a shared-algorithm boundary that speaks this Result; the adapter unwraps its parse-layer errors back to the original variant and renders only the genuinely transport-level remainder into this one.

RandomUnavailable(String)

The operating system’s random source could not be read, carrying the underlying getrandom error’s rendered message. Raised by crate::Encryptor::aes256, the only caller that draws on it.

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.
