Expand description

Controller-aware capture and restore of related canister snapshots.

Required Methods§

Source

fn capture_controller_snapshots<I>( &self, controller_id: Principal, canister_ids: I, ) -> Result<ControllerSnapshots, ControllerSnapshotError>
where I: IntoIterator<Item = Principal>,

Capture one restorable snapshot per unique canister.

Input is validated before capture begins. If a later capture fails, snapshots already captured by this operation are deleted before the structured error is returned.

Source

fn restore_controller_snapshots( &self, controller_id: Principal, snapshots: &ControllerSnapshots, ) -> Result<(), ControllerSnapshotError>

Restore a previously captured snapshot set using the same controller.

Dyn Compatibility§

This trait is not dyn compatible.

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