Trait SnapshotCheckpointer 

pub trait SnapshotCheckpointer: Send {
    // Required method
    fn save_progress<'life0, 'life1, 'async_trait>(
        &'life0 mut self,
        checkpoint: &'life1 InterleavedSnapshotCheckpoint,
    ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Receives resumable snapshot checkpoints emitted per chunk.

Required Methods

fn save_progress<'life0, 'life1, 'async_trait>( &'life0 mut self, checkpoint: &'life1 InterleavedSnapshotCheckpoint, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Persist progress made so far. Called after each chunk is durably applied to the sink and before the corresponding change-log data is freed.

Dyn Compatibility

This trait is dyn compatible.

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