Errors produced while rendering images and loading renderer resources.

Variants

SpecError(ImgGenSpecError)

Wraps a specification validation error.

BoundsTooLarge

Returned when a rendered shape exceeds safe raster bounds.

Fields

shape: &'static str

The shape whose bounds were invalid.

InvalidPathBounds

Returned when a shape path reports invalid bounds.

Fields

shape: &'static str

The shape whose path bounds were invalid.

PixmapAllocationFailed

Returned when pixmap allocation fails for a rendered shape.

Fields

shape: &'static str

The shape being rasterized.

width: u32

The requested pixmap width.

height: u32

The requested pixmap height.

RasterBufferConversionFailed

Returned when an intermediate raster buffer cannot be converted to RGBA pixels.

Fields

shape: &'static str

The shape being rasterized.

width: u32

The raster buffer width.

height: u32

The raster buffer height.

SaveImageFailed

Returned when an image cannot be written to disk.

Fields

path: String

The output path that failed.

source: ImageError

The underlying image-encoding error.

CollectImageBytesFailed

Returned when image bytes cannot be collected from the pixel buffer.

Fields

source: Error

The underlying I/O error.

OpenImageFailed

Returned when an input image file cannot be opened.

Fields

path: String

The image path that failed.

source: Error

The underlying I/O error.

DecodeImageFailed

Returned when an input image file cannot be decoded.

Fields

ReadSvgFailed

Returned when an SVG file cannot be read from disk.

Fields

path: String

The SVG path/name that failed.

source: Error

The underlying I/O error.

ParseSvgFailed

Returned when SVG parsing fails after the file is read.

Fields

path: String

The SVG path/name that failed.

source: Error

The underlying SVG parser error.

ParseSvgXmlFailed

Returned when SVG XML parsing fails.

Fields

path: String

The SVG path/name that failed.

The underlying XML parser error.

SvgScaledToZeroSize

Returned when an SVG scales down to zero pixels.

Fields

path: String

ImageNotFound

Returned when a referenced image cannot be located.

Fields

name: String

The unresolved image name.

ReadFontFileFailed

Returned when a font file cannot be read.

Fields

path: String

The font path that failed.

source: Error

The underlying I/O error.

InvalidGlyphRunFontReference

Returned when glyph shaping cannot obtain a font reference.

FontSourceError(FontSourceError)

Wraps an error returned by the fontsource client.

Trait Implementations

impl Debug for ImgGenRendererError

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

Formats the value using the given formatter.

impl Display for ImgGenRendererError

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

Formats the value using the given formatter.

impl Error for ImgGenRendererError

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<FontSourceError> for ImgGenRendererError

fn from(source: FontSourceError) -> Self

Converts to this type from the input type.

impl From<ImgGenSpecError> for ImgGenRendererError

fn from(source: ImgGenSpecError) -> Self

Converts to this type from the input type.
