Struct ContentHash 

pub struct ContentHash { /* private fields */ }

The content address of an artifact: the hash of its canonical bytes. An artifact’s identity is this value — see docs/STORAGE.md §1. Renders as sha256:<lower-hex>.

Implementations

impl ContentHash

pub fn new(algo: HashAlgo, bytes: Vec<u8>) -> Self

pub fn sha256(digest: [u8; 32]) -> Self

Construct a SHA-256 content hash from a 32-byte digest.

pub fn from_sha256_hex(hex: &str) -> Result<Self>

Parse a 64-character lowercase-hex SHA-256 (e.g. a Cargo.lock checksum) into a content hash. Errors on wrong length or non-hex input.

pub fn algo(&self) -> HashAlgo

pub fn bytes(&self) -> &[u8]

pub fn to_hex(&self) -> String

Lower-hex encoding of the digest (no algorithm prefix).
