Expand description

This class is the internal method of finding chunk boundaries.

It can look at the actual bytes or not, for example:

  • Use a rolling algorithm such as ZPAQ or Adler32
  • Find some predefined boundary in the data
  • Make blocks of a fixed size (then it’s NOT content-defined!)

This is where the internal state of the algorithm should be kept (counter, hash, etc).

Required Methods§

Source

fn find_boundary(&mut self, data: &[u8]) -> Option<usize>

Look at the new bytes to maybe find a boundary.

Provided Methods§

Source

fn reset(&mut self)

Reset the internal state after a chunk has been emitted
