Errors possible during decoding

Variants

BadSignature

Image signature is not png signature

GenericStatic(&'static str)

Generic message

Generic(String)

Generic message

BadCrc(u32, u32)

Calculated CRC does not match expected crc

ZlibDecodeErrors(InflateDecodeErrors)

error decoding zlib stream

EmptyPalette

Palette is empty yet was expected

Trait Implementations

impl Debug for PngDecodeErrors

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

Formats the value using the given formatter.

impl Display for PngDecodeErrors

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

Formats the value using the given formatter.

impl Error for PngDecodeErrors

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.

fn from(val: &'static str) -> PngDecodeErrors

Converts to this type from the input type.

impl From<InflateDecodeErrors> for PngDecodeErrors

fn from(val: InflateDecodeErrors) -> PngDecodeErrors

Converts to this type from the input type.

impl From<PngDecodeErrors> for ImageError

fn from(value: PngDecodeErrors) -> Self

Converts to this type from the input type.

impl From<String> for PngDecodeErrors

fn from(val: String) -> PngDecodeErrors
