Required Methods§

source

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.

source

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

Compresses the given data into a new vector.

source

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.

source

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

Decompresses the given data into a new vector.

source

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.

Provided Methods§

source

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

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

source

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

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