Implementations§

source§

impl Crc

source

pub fn new() -> Crc

Create a new CRC.

source

pub fn sum(&self) -> u32

Returns the current crc32 checksum.

source

pub fn amount(&self) -> u32

The number of bytes that have been used to calculate the CRC. This value is only accurate if the amount is lower than 232.

source

pub fn update(&mut self, data: &[u8])

Update the CRC with the bytes in data.

source

pub fn reset(&mut self)

Reset the CRC.

source

pub fn combine(&mut self, additional_crc: &Crc)

Combine the CRC with the CRC for the subsequent block of bytes.
