Enum ChecksumType 

pub enum ChecksumType {
    Crc32,
    Xxhash,
    Sha256,
    Blake2,
    Unknown(u16),
}

Checksum algorithm used by the filesystem, stored in the superblock’s csum_type field.

Variants

Crc32

CRC32C (Castagnoli), the default and most common checksum algorithm.

Xxhash

xxHash64, a fast non-cryptographic hash.

Sha256

SHA-256, a cryptographic hash.

Blake2

BLAKE2b-256, a cryptographic hash.

Unknown(u16)

Unrecognized checksum type value.

Implementations

impl ChecksumType

pub fn from_raw(val: u16) -> ChecksumType

Parse from the raw on-disk u16 value.

pub fn size(&self) -> usize

Size in bytes of checksums for this algorithm.

pub fn compute(self, data: &[u8]) -> Vec<u8>

Compute the checksum of data. The returned vector has length Self::size. Panics on ChecksumType::Unknown because there’s no algorithm to dispatch to.

Panics

Panics if invoked on ChecksumType::Unknown.

impl ChecksumType

pub fn to_raw(self) -> u16

Convert to the raw u16 value for on-disk storage.

Trait Implementations

impl Clone for ChecksumType

fn clone(&self) -> ChecksumType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChecksumType

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

Formats the value using the given formatter.

impl Display for ChecksumType

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

Formats the value using the given formatter.

impl PartialEq for ChecksumType

fn eq(&self, other: &ChecksumType) -> 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.
