Trait Implementations

impl Codec for LZ4Codec

fn decompress(     &mut self,     input_buf: &[u8],     output_buf: &mut Vec<u8> ) -> Result<usize>

Decompresses data stored in slice input_buf and writes output to output_buf. Returns the total number of bytes written.

fn compress(&mut self, input_buf: &[u8], output_buf: &mut Vec<u8>) -> Result<()>

Compresses data stored in slice input_buf and writes the compressed result to output_buf. Note that you'll need to call clear() before reusing the same output_buf across different compress calls.
