Rendering errors.

Variants

UnsupportedOp

Backend cannot express this command.

Fields

backend: &'static str

Backend name.

op: &'static str

Command name.

InvalidSize

Requested output size is invalid.

Fields

w: u32

Width in pixels.

h: u32

Height in pixels.

ImageDecode

Image decoding failed.

Fields

page: usize

Page index.

reason: String

What went wrong.

ImageEncode

Image encoding failed.

Trait Implementations

impl Debug for RenderError

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

Formats the value using the given formatter.

impl Display for RenderError

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

Formats the value using the given formatter.

impl Error for RenderError

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<RenderError> for OfdError

fn from(source: RenderError) -> Self

Converts to this type from the input type.
