Methods

impl Compression

fn encode(&self, bytes: Vec<u8>) -> Result<Vec<u8>, CompressionError>

It encodes bytes basing on type of compression.

fn decode(&self, bytes: Vec<u8>) -> Result<Vec<u8>, CompressionError>

It decodes bytes basing on type of compression.

fn into_string(&self) -> Option<String>

It transforms compression method into a string.

Trait Implementations

impl Debug for Compression

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq for Compression

fn eq(&self, __arg_0: &Compression) -> 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 !=.

impl Clone for Compression

fn clone(&self) -> Compression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Compression

impl From<String> for Compression

fn from(compression_string: String) -> Compression

It converts String into Compression. If string is neither lz4 nor snappy then Compression::None will be returned

impl<'a> From<&'a str> for Compression

fn from(compression_str: &'a str) -> Compression

It converts str into Compression. If string is neither lz4 nor snappy then Compression::None will be returned
