A content addressable store for arbitrary blobs.
Add the following to your Cargo.toml file:
[dependencies] blobstore = "*"
and import into your code:
extern crate blobstore;
extern crate blobstore; use blobstore::BlobStore; let mut data = "foo".as_bytes(); let store = BlobStore::new("./store".to_string()); // this will accept any `std::io::Read` type let hash = store.put(&mut data).unwrap(); // hash is a SHA256 of the content assert_eq!(hash, "2c26b46b68ffc68ff99b453c1d30413413422d706483bfa0f98a5e886266e7ae"); let mut value = String::new(); store.get(hash.as_ref()).unwrap().read_to_string(&mut value).unwrap(); assert_eq!(value, "foo"); store.remove(hash.as_ref()).unwrap(); fs::remove_dir_all(store.path).unwrap();
BlobStore implements the following trait:
trait Store { fn put(&self, item: &mut std::io::Read) -> Result<String, std::io::Error>; fn get(&self, hash: &str) -> Result<stf::fs::File, std::io::Error>; fn remove(&self, hash: &str) -> Result<(), std::io::Error>; }
