Enum font_kit::error::FontLoadingError

pub enum FontLoadingError {
    UnknownFormat,
    NoSuchFontInCollection,
    Parse,
    NoFilesystem,
    Io(Error),
}

Reasons why a loader might fail to load a font.

Variants

UnknownFormat

The data was of a format the loader didn't recognize.

NoSuchFontInCollection

Attempted to load an invalid index in a TrueType or OpenType font collection.

For example, if a .ttc file has 2 fonts in it, and you ask for the 5th one, you'll get this error.

Parse

Attempted to load a malformed or corrupted font.

NoFilesystem

Attempted to load a font from the filesystem, but there is no filesystem (e.g. in WebAssembly).

Io(Error)

A disk or similar I/O error occurred while attempting to load the font.

Trait Implementations

impl Debug for FontLoadingError

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

Formats the value using the given formatter.

impl Display for FontLoadingError

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

Formats the value using the given formatter.

impl Error for FontLoadingError

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 From<Error> for FontLoadingError

fn from(error: Error) -> FontLoadingError

Performs the conversion.
