Struct ReadLock

pub struct ReadLock<'a, Element> { /* private fields */ }

A read lock for an element in an RwStore.

The lock will automatically be released when this is dropped.

Example

let store = RwStore::new();
let id = store.insert(42);

let read_lock = store.read(id).unwrap();
assert_eq!(*read_lock, 42);

assert!(store.write_with_timeout(id, DontBlock).is_err());
mem::drop(read_lock);
assert!(store.write_with_timeout(id, DontBlock).is_ok());
