Error returned by decompression functions.

Variants

BadMagic

Frame magic number is not 0xFD2F_B528.

BadFrameHeader

Frame descriptor or field sizes are invalid.

BadBlockHeader

Block header contains invalid values.

BadBlockType

Block type field is reserved/unknown.

CorruptLiterals

Literals section is malformed or truncated.

CorruptSequences

Sequences section is malformed, or decoded output exceeds block size.

BadFseTable

FSE table description is invalid.

BadHuffmanWeights

Huffman weight table is malformed.

BadHuffmanStream

Huffman bitstream decoding failed.

WindowTooLarge

Requested window size exceeds the implementation limit.

Fields

requested: u64

max: u64

OutputTooSmall

Decompressed output would exceed the configured size limit.

ChecksumMismatch

Content checksum does not match the decompressed data.

Fields

expected: u32

got: u32

DictMismatch

Frame requires dictionary ID expected, but got was provided.

Fields

expected: u32

got: u32

DictRequired

Frame requires a dictionary but none was provided.

InvalidDictionary

Dictionary bytes failed to parse.

InputExhausted

Input ended before the frame was complete.

ExtraBytes

Unexpected trailing bytes after a valid frame.

Trait Implementations

impl Clone for DecompressError

fn clone(&self) -> DecompressError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DecompressError

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

Formats the value using the given formatter.

impl Display for DecompressError

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

Formats the value using the given formatter.

impl Eq for DecompressError

impl Error for DecompressError

Available on crate feature std only.

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<DecompressError> for ZstdError

fn from(e: DecompressError) -> Self

Converts to this type from the input type.

impl PartialEq for DecompressError

fn eq(&self, other: &DecompressError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
