Struct flate2::crc::Crc

pub struct Crc {
    amt: u32,
    hasher: Hasher,
}

The CRC calculated by a CrcReader.

Fields

amt: u32

hasher: Hasher

Implementations

impl Crc

pub fn new() -> Crc

Create a new CRC.

pub fn sum(&self) -> u32

Returns the current crc32 checksum.

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.

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

Update the CRC with the bytes in data.

pub fn reset(&mut self)

Reset the CRC.

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

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

Trait Implementations

impl Debug for Crc

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Crc

fn default() -> Self

Returns the “default value” for a type.
