A generic Storage system for blobs.

Required methods

fn put_from<R: Read>(&mut self, key: &str, r: &mut R) -> Result<usize, Error>

Save the content of r into the storage system with the given key.

fn get_to<W: Write>(&mut self, key: &str, w: &mut W) -> Result<usize, Error>

Read the contents of the blob with the given key into the given writer.

fn prefix(&mut self, prefix: &str) -> I

Find all blobs that have the given prefix and iterate over them.

fn delete(&mut self, key: &str) -> Result<(), Error>

Delete the blob with the given key.

Provided methods

fn put(&mut self, key: &str, data: &[u8]) -> Result<(), Error>

Similar to put_from but uses the give data instead of a reader.

fn get(&mut self, key: &str) -> Result<Vec<u8>, Error>

Similar to get_to but reads the contents into a byte vector.

fn remove(&mut self, name: &str) -> Result<(), Error>

Similar to delete but it does not return an error if the error is NotFound.
