Used to provide implementation for the LZ4 compression/decompression methods

Required Methods

fn compress(&self, input: &[u8], output: &mut [u8]) -> Result<usize, Lz4Error>

Compress the data.

Arguments

• input data to compress
• output buffer to write to. It must be allocated with at least Self::get_maximum_compressed_buffer_len() bytes.

Result

The number of bytes written into the output

fn decompress(&self, input: &[u8], output: &mut [u8]) -> Result<usize, Lz4Error>

Decompress the data.

Arguments

• input data to compress
• output buffer to write to. It must be allocated with the number of bytes specified in the header.

Result

The number of bytes written into the output

fn get_maximum_compressed_buffer_len(&self, decompressed_len: usize) -> usize

Find the maximum size of the output buffer when compressing.
