Trait Compress 

pub trait Compress {
    // Required methods
    fn compress(&self, block: Vec<u8>) -> Vec<u8> ;
    fn decompress(&self, block: Vec<u8>) -> Result<Vec<u8>, ()>;
}

Provide your own compression algorithm by creating an empty struct implementing compress and decompress.

Your compression algorithm is allowed to fail, but must always decompress into the same bytes. Undefined behaviour otherwise.

Note: You must always also implement CompressBoxedClone, to allow cloning and debugging of the configuration.

use swapvec::Compress;
struct DummyCompression;
impl Compress for DummyCompression {
  fn compress(&self, block: Vec<u8>) -> Vec<u8> {
      block
  }
  fn decompress(&self, block: Vec<u8>) -> Result<Vec<u8>, ()> {
      Ok(block)
  }
}

let bytes = vec![1, 2, 3];
let compression = DummyCompression;
assert_eq!(bytes, compression.decompress(compression.compress(bytes.clone())).unwrap());

Required Methods

fn compress(&self, block: Vec<u8>) -> Vec<u8>

Compress bytes blockwise. The compressed block will be put into self.decompress() later.

fn decompress(&self, block: Vec<u8>) -> Result<Vec<u8>, ()>

Receive block which was earlier compress()ed. If the result is Ok, the same bytes which were compress()es earlier are expected.
