Enum OutputError 

pub enum OutputError {
    MalformedBuffer,
    EncodingFailed(String),
}

Failure while writing the stego image to disk.

The only failure of the pipeline that no lower layer can report: layers 1 to 4 read images and never write them, so there is no error type to reuse here.

Variants

MalformedBuffer

The sample buffer did not match the geometry it claims to have.

Unreachable for a buffer that came out of crate::image_io::validate::load_and_validate, whose length is fixed by the decoder. Kept as a variant rather than as an assertion because the encoder’s constructor is fallible and swallowing that would mean writing a file the caller believes is a valid container.

EncodingFailed(String)

The PNG encoder or the filesystem refused the write.

Trait Implementations

impl Debug for OutputError

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

Formats the value using the given formatter.

impl Display for OutputError

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

Formats the value using the given formatter.

impl Error for OutputError

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<OutputError> for GenerateError

fn from(err: OutputError) -> Self

Converts to this type from the input type.

impl From<OutputError> for PipelineError

fn from(err: OutputError) -> Self

Converts to this type from the input type.
