Struct Crc64Nvme 

pub struct Crc64Nvme { /* private fields */ }

CRC-64/NVME over a payload delivered in pieces.

A direct multipart upload needs this digest twice over the same bytes: once per part, for the header the provider enforces on the way in, and once over the whole stream, for the reference completion verifies. Parts fed in order produce both without the object ever being held whole.

Implementations

impl Crc64Nvme

pub fn new() -> Self

Starts an empty digest.

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

Folds the next piece of the payload in, in order.

pub fn finish(self) -> StorageChecksum

Closes the digest over everything fed so far.

The value is the big-endian spelling of the 64-bit result, which is what the raw checksum bytes are on the wire and therefore what the hex here has to be.

Trait Implementations

impl Debug for Crc64Nvme

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

Formats the value using the given formatter.

impl Default for Crc64Nvme

fn default() -> Crc64Nvme
