Trait self_encryption::Storage

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

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.

Required methods

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

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

fn put(
    &mut self,
    name: Vec<u8>,
    data: Vec<u8>
) -> Box<dyn Future<Item = (), Error = Self::Error>>

Store data under name.

fn generate_address(&self, data: &[u8]) -> Vec<u8>

Generate the address at which the data will be stored. This address will be stored as a part of the data map.
