Trait self_encryption::Storage

pub trait Storage {
    type Error: StorageError;
    fn get(
        &self, 
        name: &[u8]
    ) -> Box<Future<Item = Vec<u8>, Error = Self::Error>>;
    fn put(
        &mut self, 
        name: Vec<u8>, 
        data: Vec<u8>
    ) -> Box<Future<Item = (), Error = Self::Error>>;
}

Trait which must be implemented by storage objects to be used in self-encryption. Data is passed to the storage object encrypted with name being the SHA3-256 hash of data. Storage could be implemented as an in-memory HashMap or a disk-based container for example.

Associated Types

type Error: StorageError

Error type returned by get or put.

fn get(&self, name: &[u8]) -> Box<Future<Item = Vec<u8>, Error = Self::Error>>

Retrieve data previously put under name. If the data does not exist, an error should be returned.
