Expand description

Operations for running a run of auto-commit DML statements inside a shared batch window.

Required Methods§

Source

fn begin_auto_commit_batch( &self, ) -> Result<Arc<AutoCommitBatchWindow>, StorageError>

Source

fn bind_auto_commit_statement( &self, window: &Arc<AutoCommitBatchWindow>, ) -> Result<Self, StorageError>
where Self: Sized,

Source

fn finalize_auto_commit_batch( &self, window: &AutoCommitBatchWindow, ) -> Result<(), StorageError>

Provided Methods§

Source

fn bind_auto_commit_writer( &self, _window: &Arc<AutoCommitBatchWindow>, ) -> Result<Box<dyn StorageWriter + '_>, StorageError>

Object-safe variant of Self::bind_auto_commit_statement: returns the bound statement storage as a boxed crate::StorageWriter carrying the window’s operation context (shared undo log in group mode), so writers behind a dyn QueryStorage handle can join the window. The default implementation is not_supported.

Dyn Compatibility§

This trait is dyn compatible.

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