Enum Error 

#[non_exhaustive]
pub enum Error {
    NoObject(u64),
    TooDeep(u32),
    XrefBroken,
    NoCatalog,
    Unresolved(ObjRef),
    Cycle(ObjRef),
    NoPage(PageIndex),
    Limit(LimitExceeded),
}

A failure below the document level: a token that is not an object, a cross-reference section that cannot be read, a fetch that finds nothing.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoObject(u64)

The bytes at this position are not the start of any object.

TooDeep(u32)

Objects nested deeper than the configured limit.

XrefBroken

No cross-reference information could be read or reconstructed.

NoCatalog

The trailer named no catalog, or the object it named is not one.

Unresolved(ObjRef)

A reference names an object the cross-reference table has no entry for, has marked free, or whose body would not parse.

Cycle(ObjRef)

This fetch re-entered one already in progress.

NoPage(PageIndex)

A page index past the document’s page count, or one whose tree walk found nothing.

Limit(LimitExceeded)

The caller’s Limits::deadline passed while the cross-reference was being rebuilt by scanning the file.

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

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 Eq for Error

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(e: Error) -> Self

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 !=.
