Struct crc_any::CRCu64

pub struct CRCu64 { /* private fields */ }

This struct can help you compute a CRC-64 (or CRC-x where x is equal or less than 64) value.

Implementations

impl CRCu64

pub fn create_crc( poly: u64, bits: u8, initial: u64, final_xor: u64, reflect: bool ) -> CRCu64

Create a CRCu64 instance by providing the length of bits, expression, reflection, an initial value and a final xor value.

pub fn digest<T: ?Sized + AsRef<[u8]>>(&mut self, data: &T)

Digest some data.

pub fn reset(&mut self)

Reset the sum.

pub fn get_crc(&self) -> u64

Get the current CRC value (it always returns a u64 value). You can continue calling digest method even after getting a CRC value.

impl CRCu64

pub fn get_crc_vec_le(&mut self) -> Vec<u8>

Get the current CRC value (it always returns a vec instance with a length corresponding to the CRC bits). You can continue calling digest method even after getting a CRC value.

pub fn get_crc_vec_be(&mut self) -> Vec<u8>

Get the current CRC value (it always returns a vec instance with a length corresponding to the CRC bits). You can continue calling digest method even after getting a CRC value.
