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

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§

source§

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

source

pub fn charge_or_zero(&self) -> Balance

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

source

pub fn is_zero(&self) -> bool

source§

impl<Balance> StorageDeposit<Balance>where Balance: Saturating + Ord + Copy,

source

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

This is essentially a saturating signed add.

source

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

This is essentially a saturating signed sub.

source

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.
