Methods

impl FastCDC

fn new() -> Self

Create new FastCDC engine with default chunking settings

fn new_with_chunk_bits(chunk_bits: u32) -> Self

Create new FastCDC engine with custom chunking settings

chunk_bits is number of bits that need to match in the edge condition. CHUNK_BITS constant is the default.
