Struct FileStore 

pub struct FileStore { /* private fields */ }

Stores the snapshot blob as a single file.

Writes are atomic (temp file + rename) and, on Unix, the file is created with 0600 permissions. The blob holds private keys in the clear: protect the containing directory, or supply a custom ControllerStore backed by an encrypted store.
