Expand description

Checkpoint abstraction for durable source progress.

Required Methods§

Source

fn save<'life0, 'life1, 'async_trait>( &'life0 mut self, offset: &'life1 dyn Offset, committed_event_count: u64, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Source

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

Source

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

Dyn Compatibility§

This trait is dyn compatible.

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