A collection of prepared statements.

Required Methods

fn new<'life0, 'async_trait>( session: &'life0 Session, ) -> Pin<Box<dyn Future<Output = Result<Self, ScyllaxError>> + Send + 'async_trait>>

where Self: Sized + 'async_trait, 'life0: 'async_trait,

Create a new collection of prepared statements.

fn register_tasks(self, executor: Arc<Executor<Self>>) -> Self

where Self: Sized,

Register all tasks with the executor.

Provided Methods

fn get_prepared<T: Query>(&self) -> &PreparedStatement

where Self: GetPreparedStatement<T>,

Gets a prepared statement from the collection.

fn get_task<T: Query + ReadQuery>(&self) -> &Sender<ShardMessage<T>>

where Self: GetCoalescingSender<T>,

Gets a task from the collection.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
