An error that can occur when using compression.

Variants

CreateZstandardEncoder

An error occurred while creating a Zstandard encoder.

Fields

context: &'static str

The context in which the error occurred.

This is meant to complete the sentence “Error creating a Zstandard encoder while {context} with {compression_settings}”.

compression_settings: CompressionSettings

The compression settings chosen for the encoder.

source: Error

The source error.

CreateZstandardDecoder(Error)

An error occurred while creating a Zstandard decoder.

FinishEncoder

An error occurred while finishing a compression encoder.

Fields

compression_type: CompressionAlgorithmFileExtension

The compression chosen for the encoder.

source: Error

The source error

GetParallelism(Error)

An error occurred while trying to get the available parallelism.

IntegerConversion(TryFromIntError)

An error occurred while trying to convert an integer.

IoRead

An I/O error occurred while reading.

Fields

context: &'static str

The context in which the error occurred.

This is meant to complete the sentence “I/O read error while “.

source: Error

The source error.

IoWrite

An I/O error occurred while writing.

Fields

context: &'static str

The context in which the error occurred.

This is meant to complete the sentence “I/O write error while “.

source: Error

The source error.

InvalidCompressionLevel

A compression level is not valid.

Fields

level: u8

The invalid compression level.

min: u8

The minimum valid compression level.

max: u8

The maximum valid compression level.

UnknownCompressionAlgorithmFileExtension(Error)

A compression algorithm file extension is not known.

UnsupportedCompressionAlgorithm

An unsupported compression algorithm was used.

Fields

value: String

The unsupported compression algorithm.

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, __formatter: &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.
