Trait MaybeFullDatabase 

pub trait MaybeFullDatabase: DatabaseRef<Error = DatabaseError> + Debug {
    // Required methods
    fn clear_into_state_snapshot(&mut self) -> StateSnapshot;
    fn read_as_state_snapshot(&self) -> StateSnapshot;

    // Provided methods
    fn maybe_as_full_db(&self) -> Option<&AddressMap<DbAccount>> { ... }
    fn is_persistent(&self) -> bool { ... }
}

Helper trait get access to the full state data of the database

Required Methods

fn clear_into_state_snapshot(&mut self) -> StateSnapshot

Clear the state and move it into a new StateSnapshot.

fn read_as_state_snapshot(&self) -> StateSnapshot

Read the state snapshot.

This clones all the states and returns a new StateSnapshot.

fn clear(&mut self)

Clears the entire database

fn init_from_state_snapshot(&mut self, state_snapshot: StateSnapshot)

Reverses clear_into_snapshot by initializing the db’s state with the state snapshot.

Provided Methods

fn maybe_as_full_db(&self) -> Option<&AddressMap<DbAccount>>

fn is_persistent(&self) -> bool

Returns whether snapshots of this database use structural sharing.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
