fn extend_freeze( asset: <Pallet<T, I> as Inspect<<T as Config>::AccountId>>::AssetId, id: &<Pallet<T, I> as Inspect<<T as Config>::AccountId>>::Id, who: &<T as Config>::AccountId, amount: <Pallet<T, I> as Inspect<<T as Config>::AccountId>>::Balance, ) -> Result<(), DispatchError>

Prevent the balance of the account of who from being reduced below the given amount and identify this restriction though the given id. Unlike set_freeze, this does not counteract any pre-existing freezes in place for who under the id. Also unlike set_freeze, in the case that amount is zero, this is no-op and never fails.

fn decrease_frozen( asset: Self::AssetId, id: &Self::Id, who: &AccountId, amount: Self::Balance, ) -> Result<(), DispatchError>

Decrease the amount which is being frozen for a particular lock, failing in the case of underflow.
