Trait PocketIcSnapshotExt 

pub trait PocketIcSnapshotExt {
    // Required methods
    fn capture_snapshots<I>(
        &self,
        targets: I,
    ) -> Result<ControllerSnapshots, ControllerSnapshotError>
       where I: IntoIterator<Item = CanisterSnapshotTarget>;
    fn restore_snapshots(
        &self,
        snapshots: &ControllerSnapshots,
        funding: SnapshotRestoreFunding,
    ) -> Result<(), ControllerSnapshotError>;
}

Exact-sender capture and restore of related canister snapshots.

Required Methods

fn capture_snapshots<I>( &self, targets: I, ) -> Result<ControllerSnapshots, ControllerSnapshotError>

where I: IntoIterator<Item = CanisterSnapshotTarget>,

Capture snapshots with one explicit sender per canister.

Input is duplicate-checked before any effects and captured in deterministic canister-id order. A later failure rolls back snapshots captured earlier in the set. No other sender is attempted after a rejection.

fn restore_snapshots( &self, snapshots: &ControllerSnapshots, funding: SnapshotRestoreFunding, ) -> Result<(), ControllerSnapshotError>

Restore each snapshot with its exact captured sender and selected funding.

Preserve never adds cycles; TopUpTo is evaluated before each restore. PocketIC may charge cycles for the restore itself. Rejection or panic stops the set without retrying another sender or rewinding earlier restores.

Dyn Compatibility

This trait is not dyn compatible.

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