Enum BackendError 

pub enum BackendError {
    Parse(String),
    Io(Error),
    Font(String),
    Interpreter(String),
    Core(PdfError),
}

Error type for PDF parsing backend operations.

Wraps backend-specific errors and provides conversion to PdfError for unified error handling across the library.

Variants

Parse(String)

Error from PDF parsing (structure, syntax, object resolution).

Io(Error)

Error reading PDF data.

Font(String)

Error resolving font or encoding information.

Interpreter(String)

Error during content stream interpretation.

Core(PdfError)

A core library error.

Trait Implementations

impl Debug for BackendError

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

Formats the value using the given formatter.

impl Display for BackendError

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

Formats the value using the given formatter.

impl Error for BackendError

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.
