Struct rdedup_cdc::gear::Gear

pub struct Gear {
    pub chunk_bits: u32,
    // some fields omitted
}

Fields

chunk_bits: u32

Methods

impl Gear

fn new() -> Self

Create new Gear engine with default chunking settings

fn new_with_chunk_bits(chunk_bits: u32) -> Self

Create new Gear 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.
