Enum CascadePolicy
pub enum CascadePolicy {
RefuseOnHard,
DryRun,
}Expand description
How a delete handles references and whether it mutates.
Variants§
RefuseOnHard
Refuse if any HARD reference blocks; otherwise scrub the soft references and remove the entry. The default.
DryRun
Compute the plan and mutate nothing (the dry-run a surface renders).
