pub struct MVHashMapView<'a, K, V> { /* private fields */ }

Expand description

A struct that is always used by a single thread performing an execution task. The struct is passed to the VM and acts as a proxy to resolve reads first in the shared multi-version data-structure. It also allows the caller to track the read-set and any dependencies.

TODO(issue 10177): MvHashMapView currently needs to be sync due to trait bounds, but should not be. In this case, the read_dependency member can have a RefCell type and the captured_reads member can have RefCell<Vec<ReadDescriptor>> type.
