An error that can occur while rendering 2D graphics.

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.

InvalidInput

A function was passed an invalid input.

NotSupported

Something is impossible on the current platform.

Unimplemented

Something is possible, but not yet implemented.

MissingFeature(&'static str)

Piet was compiled without a required feature.

StackUnbalance

A stack pop failed.

BackendError(Box<dyn Error>)

The backend failed unexpectedly.

MissingFont

A font could not be found.

FontLoadingFailed

Font data could not be loaded.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Box<dyn Error + 'static, Global>> for Error

fn from(e: Box<dyn Error>) -> Error

Performs the conversion.
