Enum pallet_revive::StorageDeposit

pub enum StorageDeposit<Balance> {
    Refund(Balance),
    Charge(Balance),
}

The amount of balance that was either charged or refunded in order to pay for storage.

Variants

Refund(Balance)

The transaction reduced storage consumption.

This means that the specified amount of balance was transferred from the involved deposit accounts to the origin.

Charge(Balance)

The transaction increased storage consumption.

This means that the specified amount of balance was transferred from the origin to the involved deposit accounts.

Implementations

impl<Balance: Zero + Copy> StorageDeposit<Balance>

pub fn charge_or_zero(&self) -> Balance

Returns how much balance is charged or 0 in case of a refund.

pub fn is_zero(&self) -> bool

impl<Balance> StorageDeposit<Balance>

where Balance: Saturating + Ord + Copy,

pub fn saturating_add(&self, rhs: &Self) -> Self

This is essentially a saturating signed add.

pub fn saturating_sub(&self, rhs: &Self) -> Self

This is essentially a saturating signed sub.

pub fn available(&self, limit: &Balance) -> Balance

If the amount of deposit (this type) is constrained by a limit this calculates how much balance (if any) is still available from this limit.

Note

In case of a refund the return value can be larger than limit.

fn default() -> Self

Returns the “default value” for a type.

impl<Balance> Encode for StorageDeposit<Balance>

where Balance: Encode,

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.
