pub enum FaceParsingError {
    MalformedFont,
    UnknownMagic,
    FaceIndexOutOfBounds,
    NoHeadTable,
    NoHheaTable,
    NoMaxpTable,
}

A list of font face parsing errors.

Variants

MalformedFont

An attempt to read out of bounds detected.

Should occur only on malformed fonts.

UnknownMagic

Face data must start with 0x00010000, 0x74727565, 0x4F54544F or 0x74746366.

FaceIndexOutOfBounds

The face index is larger than the number of faces in the font.

NoHeadTable

The head table is missing or malformed.

NoHheaTable

The hhea table is missing or malformed.

NoMaxpTable

The maxp table is missing or malformed.

Trait Implementations

impl Clone for FaceParsingError

fn clone(&self) -> FaceParsingError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for FaceParsingError

impl Debug for FaceParsingError

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

Formats the value using the given formatter.

impl Display for FaceParsingError

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

Formats the value using the given formatter.

impl Error for FaceParsingError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<FaceParsingError> for FaceParsingError

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
