Struct gzip_header::Crc

pub struct Crc { /* fields omitted */ }

A wrapper struct containing a CRC checksum in the format used by gzip and the amount of bytes input to it mod 2^32.

Methods

impl Crc

fn new() -> Crc

fn with_initial(checksum: u32, amount: u32) -> Crc

fn sum(&self) -> u32

Return the current checksum value.

fn amt_as_u32(&self) -> u32

Return the number of bytes input.

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

Update the checksum and byte counter with the provided data.

fn reset(&mut self)

Reset the checksum and byte counter.
