Enum Error 

#[non_exhaustive]
pub enum Error {
    Empty,
    PfbSegment {
        at: usize,
    },
    NoEexec,
    EexecGarbage,
    NoCharStrings,
}

Why a Type 1 font program could not be read.

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.

Empty

The blob is shorter than the smallest thing that could be a font.

PfbSegment

A PFB container’s segment headers did not describe the blob: a segment length running past the end, a tag byte other than 0x80, or a segment type outside 1–3.

Carries the offset of the offending header, which is what a fuzz reduction wants.

Fields

at: usize

Byte offset of the header that failed.

NoEexec

No eexec token was found, so the font has no private portion — and a Type 1 font’s charstrings live entirely inside it.

EexecGarbage

The eexec section decrypted to something that is not a PostScript private dictionary, which means the wrong bytes were fed to the cipher.

NoCharStrings

The program parsed but declared no /CharStrings, so there is nothing to draw.

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 PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
