Provided Associated Types§

Source

type CommitMetadata: Send = ()

Required Methods§

Source

fn begin_epoch<'life0, 'async_trait>( &'life0 mut self, epoch: u64, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Begin a new epoch

Source

fn write_batch<'life0, 'async_trait>( &'life0 mut self, chunk: StreamChunk, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Write a stream chunk to sink

Source

fn barrier<'life0, 'async_trait>( &'life0 mut self, is_checkpoint: bool, ) -> Pin<Box<dyn Future<Output = Result<Self::CommitMetadata>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Receive a barrier and mark the end of current epoch. When is_checkpoint is true, the sink writer should commit the current epoch.

Provided Methods§

Source

fn abort<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Clean up

Dyn Compatibility§

This trait is dyn compatible.

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