Errors that can occur when de/compressing lz4.

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.

CompressionError(CompressError)

Compression error.

DecompressionError(DecompressError)

Decompression error.

IoError(Error)

An io::Error was encountered.

UnsupportedBlocksize(u8)

Unsupported block size.

UnsupportedVersion(u8)

Unsupported frame version.

WrongMagicNumber

Wrong magic number for the LZ4 frame format.

ReservedBitsSet

Reserved bits set.

InvalidBlockInfo

Block header is malformed.

BlockTooBig

Read a block larger than specified in the Frame header.

HeaderChecksumError

The Frame header checksum doesn’t match.

BlockChecksumError

The block checksum doesn’t match.

ContentChecksumError

The content checksum doesn’t match.

SkippableFrame(u32)

Read an skippable frame. The caller may read the specified amount of bytes from the underlying io::Read.

DictionaryNotSupported

External dictionaries are not supported.

ContentLengthError

Content length differs.

Fields

expected: u64

Expected content length.

actual: u64

Actual content lenght.

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(e: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
