Struct EnterSafeModeOnFailedMigration

Source 
pub struct EnterSafeModeOnFailedMigration<SM, Else: FailedMigrationHandler>(/* private fields */);
Expand description

Enter safe mode on a failed runtime upgrade.

This can be very useful to manually intervene and fix the chain state. Else is used in case that the safe mode could not be entered.
