impl<C: Send + Sync + Context> OutputType for ExecutionStateView<C>where ViewError: From<C::Error>,

fn type_name() -> Cow<'static, str>

Type the name.

fn create_type_info(registry: &mut Registry) -> String

Create type information in the registry and return qualified typename.

fn resolve<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, ctx: &'life1 ContextSelectionSet<'life2>, _field: &'life3 Positioned<Field> ) -> Pin<Box<dyn Future<Output = ServerResult<Value>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

impl<C> View<C> for ExecutionStateView<C>where C: Context + Send + Sync + Clone + 'static, ViewError: From<C::Error>,

fn context(&self) -> &C

Obtains a mutable reference to the internal context.

fn load<'async_trait>( context: C ) -> Pin<Box<dyn Future<Output = Result<Self, ViewError>> + Send + 'async_trait>>where Self: 'async_trait,

Creates a view or a subview.

fn rollback(&mut self)

Discards all pending changes. After that flush should have no effect to storage.

fn flush(&mut self, batch: &mut Batch) -> Result<(), ViewError>

Persists changes to storage. This leaves the view still usable and is essentially neutral to the program running. Crash-resistant storage implementations are expected to accumulate the desired changes in the batch variable first. If the view is dropped without calling flush, staged changes are simply lost.

fn delete(self, batch: &mut Batch)

Instead of persisting changes, clears all the data that belong to this view and its subviews. Crash-resistant storage implementations are expected to accumulate the desired changes into the batch variable first. No data/metadata at all is left after delete. The view is consumed by delete and cannot be used in any way after delete.

fn clear(&mut self)

Clears the view. That can be seen as resetting to default. In the case of a RegisterView this means setting the value to T::default(). For LogView, QueueView, this leaves the range data to be left in the database.
