Enum TextToPngError

#[non_exhaustive]
pub enum TextToPngError {
    InvalidColor,
    InvalidFontSize,
    NoFontFound,
    InvalidInput,
    CouldNotCreateImageStorage,
    TextProcessError(Error),
    PngGeneratorError(EncodingError),
}

Error type returned on unsuccessful rendering calls

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.

InvalidColor

Error case when the color string given is not parsable into a valid color

InvalidFontSize

Error indicating the given font size was invalid

NoFontFound

Error indicating the font data given did not contain a valid font

InvalidInput

Indicates an error with the inputs, but we can’t pin down what it was

CouldNotCreateImageStorage

Error indicating the memory for the rendered text couldn’t be allocated. Note. This won’t happen until memory allocation is fallible ala https://github.com/rust-lang/rust/issues/48043

TextProcessError(Error)

Error case to handle failures form usvg

PngGeneratorError(EncodingError)

Error case to handle failures from resvg and tiny-skia

Trait Implementations

impl Debug for TextToPngError

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

Formats the value using the given formatter.

impl Display for TextToPngError

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

Formats the value using the given formatter.

impl Error for TextToPngError

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<EncodingError> for TextToPngError

fn from(source: EncodingError) -> Self

Converts to this type from the input type.

impl From<Error> for TextToPngError

fn from(source: SvgError) -> Self

Converts to this type from the input type.
