The error type for JPEG XL entropy decoders.

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.

Bitstream(Error)

Bitstream-level error.

Lz77NotAllowed

LZ77 decoder is being used where it’s not allowed.

InvalidAnsHistogram

Decoded ANS distribution is invalid.

InvalidAnsStream

ANS stream checksum verification has failed.

InvalidIntegerConfig

Hybrid integer configuration is invalid.

Fields

split_exponent: u32

msb_in_token: u32

lsb_in_token: Option<u32>

InvalidPermutation

Decoded permutation is invalid.

InvalidPrefixHistogram

Decoded Brotli histogram is invalid.

PrefixSymbolTooLarge(usize)

Prefix code symbol is too large.

InvalidCluster(u32)

Decoded cluster ID is invalid.

ClusterHole

Distribution cluster has a hole.

Fields

num_expected_clusters: u32

num_actual_clusters: u32

UnexpectedLz77Repeat

LZ77 repeat symbol encountered without decoding any symbols.

InvalidLz77Symbol

Decoded LZ77 symbol is invalid.

Implementations

impl Error

pub fn unexpected_eof(&self) -> bool

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.
