Struct BZip2

pub struct BZip2;

Available on crate features compression and bzip only.

A CompressionFormat corresponding to the bzip compression algorithm. Implemented using the bzip2 crate.

Trait Implementations

impl Clone for BZip2

fn clone(&self) -> BZip2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CompressionFormat for BZip2

type Encoder<W: Write> = BzEncoder<W>

The encoder wrapper type that compresses data sent to the contained writer.

type Decoder<R: Read> = BzDecoder<R>

The decoder wrapper type that decompresses data sent from the contained reader.

fn encode_writer<W: Write>(&self, writer: W, level: u32) -> Self::Encoder<W>

Wraps a writer that takes uncompressed data, producing a new writer that outputs compressed data.

fn decode_reader<R: Read>(&self, reader: R) -> Self::Decoder<R>

Wraps a reader that takes compressed data, producing a new reader that outputs uncompressed data.

impl CompressionFormatLevels for BZip2

const COMPRESSION_LEVEL_NONE: u32 = 0u32

The level for no compression.

const COMPRESSION_LEVEL_FAST: u32 = 1u32

The level for ‘fast’ compression.

const COMPRESSION_LEVEL_BEST: u32 = 9u32

The level for ‘best’ compression.

const COMPRESSION_LEVEL_DEFAULT: u32 = 6u32

The level for default compression.

impl Debug for BZip2

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

Formats the value using the given formatter.

impl Default for BZip2

fn default() -> BZip2

Returns the “default value” for a type.

impl PartialEq for BZip2

fn eq(&self, other: &BZip2) -> 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.
