Enum Error

#[non_exhaustive]
pub enum Error {
    InvalidInput,
    NotSupported,
    Unimplemented,
    MissingFeature(&'static str),
    StackUnbalance,
    BackendError(Box<dyn Error>),
    MissingFont,
    FontLoadingFailed,
}

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<(), Error>

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Box<dyn Error>> for Error

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

Converts to this type from the input type.
