Enum TextRasterError 

#[non_exhaustive]
pub enum TextRasterError {
    NoFonts,
    InvalidFont(String),
    InvalidRequest,
    TooLarge,
}

Typed text-host failure.

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.

NoFonts

No usable fonts were registered.

InvalidFont(String)

OpenType parsing failed.

InvalidRequest

Request values are non-finite or outside the supported range.

TooLarge

Computed dimensions cannot be represented safely.

Trait Implementations

impl Clone for TextRasterError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextRasterError

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

Formats the value using the given formatter.

impl Display for TextRasterError

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

impl Eq for TextRasterError

impl Error for TextRasterError

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 TextRasterError

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

Equality operator ==.

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

Inequality operator !=.
