}Expand description
A trait for storages that support exporting and importing snapshots of their data.
Required Methods§
Sourcefn export_snapshot(&self) -> BoxStream<'static, Result<SnapshotData>>
fn export_snapshot(&self) -> BoxStream<'static, Result<SnapshotData>>
Export a snapshot of the storage.
Sourcefn import_snapshot<'life0, 'async_trait>(
&'life0 self,
snapshot: BoxStream<'static, Result<SnapshotData>>,
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
fn import_snapshot<'life0, 'async_trait>(
&'life0 self,
snapshot: BoxStream<'static, Result<SnapshotData>>,
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
Import a snapshot of the storage.
The snapshot stream must be consumed to completion.
Whether data is overwritten or merged is up to the implementation.
