Enum EncodingError 

#[non_exhaustive]
pub enum EncodingError {
    UnsupportedFormat(Format),
    InvalidSize(NonZeroU32, NonZeroU32),

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.

UnsupportedFormat(Format)

Returned by Encoder and encode() when the format does not support encoding.

InvalidSize(NonZeroU32, NonZeroU32)

UnexpectedSurfaceSize

Returned by Encoder when the user tries to write a surface with a size that is different from the size declared in the header.

TooManySurfaces

Returned by Encoder when the encoder has already written all surfaces declared in the header, but the user attempts to write additional surfaces.

MissingSurfaces

Returned by Encoder::finish() when the encoder has not written all surfaces declared in the header.

Cancelled

Returned when an operation given a CancellationToken or Progress was cancelled before or during the operation.

Layout(LayoutError)

Io(Error)

Trait Implementations

impl Debug for EncodingError

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

Formats the value using the given formatter.

impl Display for EncodingError

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

Formats the value using the given formatter.

impl Error for EncodingError

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<Error> for EncodingError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<LayoutError> for EncodingError

fn from(err: LayoutError) -> Self

Converts to this type from the input type.
