Trait Implementations

impl Clone for DefaultCompressor

fn clone(&self) -> DefaultCompressor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Compressor for DefaultCompressor

type Error = Error

Compression/Decompression Error

fn compress_to( src: &[u8], dst: &mut [u8], cmp: Compression ) -> Result<usize, Self::Error>

Compresses the given data into the given output buffer, returning the number of bytes written.

fn compress_into_vec( src: &[u8], cmp: Compression ) -> Result<Vec<u8>, Self::Error>

Compresses the given data into a new vector.

fn decompress_to( src: &[u8], dst: &mut [u8], cmp: Compression ) -> Result<usize, Self::Error>

Decompresses the given data into the given output buffer, returning the number of bytes written.

fn decompress_into_vec( src: &[u8], cmp: Compression ) -> Result<Vec<u8>, Self::Error>

Decompresses the given data into a new vector.

fn max_compressed_size(src: &[u8], cmp: Compression) -> usize

Returns the maximum size of the compressed data according to the compression algorithm and src size.

fn compress_into_bytes( src: &[u8], cmp: Compression ) -> Result<Bytes, Self::Error>

Compresses the given data into a new bytes::Bytes.

fn decompress_into_bytes( src: &[u8], cmp: Compression ) -> Result<Bytes, Self::Error>

Decompresses the given data into a new bytes::Bytes.

impl Debug for DefaultCompressor

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

Formats the value using the given formatter.

impl Default for DefaultCompressor

fn default() -> DefaultCompressor

Returns the “default value” for a type.

impl Hash for DefaultCompressor

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<DefaultCompressor> for DefaultCompressor

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

This method tests for self and other values to be equal, and is used by ==.

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

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