gix-hash 0.24.0

This crate provides types for identifying git objects using a hash digest.

These are provided in [borrowed versions][oid] as well as an [owned one][ObjectId].

Examples

use gix_hash::{hasher, Kind, ObjectId, Prefix};

let id = ObjectId::from_hex(b"e69de29bb2d1d6434b8b29ae775ad8c2e48c5391").unwrap();
assert_eq!(id.kind(), Kind::Sha1);
assert!(id.is_empty_blob());

let prefix = Prefix::new(&id, 7).unwrap();
assert_eq!(prefix.to_string(), "e69de29");

let mut digest = hasher(Kind::Sha1);
digest.update(id.as_slice());
let hashed_bytes = digest.try_finalize().unwrap();
assert_eq!(hashed_bytes.kind(), Kind::Sha1);
assert_ne!(hashed_bytes, id);
