Struct exonum::storage::Error

pub struct Error { /* fields omitted */ }

The error type for I/O operations with storage.

These errors result in a panic. Storage errors are fatal as in the case of database issues, the system stops working. Assuming that there are other nodes and secret keys and other crucial data are not stored in the data base, the operation of the system can be resumed from a backup or by rebooting the node.
