Struct Digest 

pub struct Digest {
    pub algorithm: String,
    pub hash: String,
    pub size: u64,
}

Algorithm-tagged digest and exact byte length of a cache object.

Fields

algorithm: String

Hash algorithm name (blake3 or sha256).

hash: String

Lowercase hexadecimal hash value.

size: u64

Exact uncompressed object length in bytes.

Implementations

impl Digest

pub fn blake3(bytes: &[u8]) -> Self

Compute a BLAKE3 digest for in-memory bytes.

pub fn blake3_file(path: &Path) -> Result<Self>

Hash a file with BLAKE3 while counting bytes in the same pass.

pub fn validate(&self) -> Result<()>

Validate the algorithm and lowercase hexadecimal representation.

pub fn matches_bytes(&self, bytes: &[u8]) -> Result<bool>

Return whether bytes have this digest and declared length.

pub fn matches_file(&self, path: &Path) -> Result<bool>

Stream a file and return whether it has this digest and length.

pub fn key(&self) -> String

Stable storage key containing the algorithm, hash, and byte length.

pub fn algorithm_kind(&self) -> Result<DigestAlgorithm>

Parse the algorithm tag into its closed version-one enum.

Trait Implementations

impl Ord for Digest

fn cmp(&self, other: &Digest) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
