Enum SubsetError 

pub enum SubsetError {
    Parse(ParseError),
    Write(WriteError),
    CFF(CFFError),
    NotDef,
    TooManyGlyphs,
    InvalidFontCount,
}

Error type returned from subsetting.

Variants

Parse(ParseError)

An error occurred reading or parsing data.

Write(WriteError)

An error occurred serializing data.

CFF(CFFError)

An error occurred when interpreting CFF CharStrings

NotDef

The glyph subset did not include glyph 0/.notdef in the first position

TooManyGlyphs

The subset glyph count exceeded the maximum number of glyphs

InvalidFontCount

The CFF font did not contain a sole font, which is the only supported configuration for subsetting

Trait Implementations

impl Debug for SubsetError

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

Formats the value using the given formatter.

impl Display for SubsetError

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

Formats the value using the given formatter.

impl Error for SubsetError

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.
