Struct Crc

pub struct Crc { /* private fields */ }

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

Implementations

impl Crc

pub const fn new() -> Crc

Create a new empty CRC struct.

pub const fn with_initial(checksum: u32, amt: u32) -> Crc

pub const fn sum(&self) -> u32

Return the current checksum value.

pub const fn amt_as_u32(&self) -> u32

Return the number of bytes input.

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

Update the checksum and byte counter with the provided data.

pub fn reset(&mut self)

Reset the checksum and byte counter.

Trait Implementations

impl Clone for Crc

fn clone(&self) -> Crc

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Crc

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

Formats the value using the given formatter.

impl Default for Crc

fn default() -> Crc

Returns the “default value” for a type.

impl Display for Crc

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

Formats the value using the given formatter.

impl Hash for Crc

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Crc

fn eq(&self, other: &Crc) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
