Struct ReadOnlyStorage

pub struct ReadOnlyStorage<S: Storage<I>, I: Item> { /* private fields */ }

A wrapper around a Storage that disallows any write operations.

Example

let orig = VdirStorage::<IcsItem>::new(
    Utf8PathBuf::from("/path/to/storage/"),
    String::from("ics"),
);

let read_only = ReadOnlyStorage::from(orig);
