Struct matterdb::OwnedReadonlyFork[−][src]

pub struct OwnedReadonlyFork(_);

Version of ReadonlyFork with a static lifetime. Can be produced from an Rc<Fork> using the AsReadonly trait.

Beware that producing an instance increases the reference counter of the underlying fork. If you need to obtain Fork from Rc<Fork> via Rc::try_unwrap, make sure that all OwnedReadonlyFork instances are dropped by this time.

Examples

let db = TemporaryDB::new();
let fork = Rc::new(db.fork());
fork.get_list("list").extend(vec![1_u32, 2, 3]);
let ro_fork: OwnedReadonlyFork = fork.as_readonly();
let list = ro_fork.get_list::<_, u32>("list");
assert_eq!(list.len(), 3);
