Enum EncodeError 

pub enum EncodeError {
    Io(Error),
    UnsupportedMode(&'static str),
    PngEncoder(EncodingError),
}

Errors that can occur during encoding.

Variants

Io(Error)

An I/O error writing to the output sink.

UnsupportedMode(&'static str)

The pixel mode is not supported by the chosen encoder.

The message describes what the caller should do instead.

PngEncoder(EncodingError)

An internal error from the png encoder (non-I/O).

Trait Implementations

impl Debug for EncodeError

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

Formats the value using the given formatter.

impl Display for EncodeError

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

Formats the value using the given formatter.

impl Error for EncodeError

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 EncodeError

fn from(e: EncodingError) -> Self

Converts to this type from the input type.

impl From<Error> for EncodeError

fn from(e: Error) -> Self

Converts to this type from the input type.
