Trait Implementations

impl CharStringVisitor<f32, CFFError> for DebugVisitor

fn visit( &mut self, op: VisitOp, stack: &ArgumentsStack<'_, f32>, ) -> Result<(), CFFError>

Called for each operator in the CharString, except for callsubr and callgsubr — these are handled by enter/exit_subr.

fn enter_subr(&mut self, index: SubroutineIndex) -> Result<(), CFFError>

Called prior to entering a subroutine.

fn exit_subr(&mut self) -> Result<(), E>

Called when returning from a subroutine.

fn enter_seac(&mut self, _seac: SeacChar, _dx: T, _dy: T) -> Result<(), E>

Called before entering a component of an accented character.

fn exit_seac(&mut self, _seac: SeacChar) -> Result<(), E>

Called when returning from a component of an accented character.

fn hint_data(&mut self, _op: VisitOp, _hints: &[u8]) -> Result<(), E>

Called with the hint data that follows the hintmask and cntrmask operators.

impl Clone for CFFError

fn clone(&self) -> CFFError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CFFError

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

Formats the value using the given formatter.

impl Display for CFFError

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

Formats the value using the given formatter.

impl Error for CFFError

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<CFFError> for SubsetError

fn from(err: CFFError) -> SubsetError

Converts to this type from the input type.

impl From<CFFError> for VariationError

fn from(err: CFFError) -> VariationError

Converts to this type from the input type.

impl From<ParseError> for CFFError

fn from(error: ParseError) -> CFFError

Converts to this type from the input type.

impl PartialEq for CFFError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
