Struct RestoreInput 

pub struct RestoreInput<'a> {
    pub run_id: &'a RunId,
    pub run_dir: &'a RunDir,
    pub record: &'a RunRecord,
    pub held: Option<&'a HeldLock>,
    pub cause: Option<RollbackCause>,
}

What restore_snapshot is asked to undo.

Fields

run_id: &'a RunId

The run doing the restoring: for an abort or an auto-rollback the run itself, for a manual rollback the rollback run (it becomes the record’s rolled_back_by).

run_dir: &'a RunDir

That run’s directory (named in rollback_failed; the snapshot copy is downloaded into it).

record: &'a RunRecord

The record of the run being undone: its touched set and pre-images.

held: Option<&'a HeldLock>

The scan-lock this engine still holds, when it does.

cause: Option<RollbackCause>

Why an apply is being undone; None for a manual rollback (23-11), which keeps the closed data.cause vocabulary of an apply as it is.
