Enum DependentCost

source
pub enum DependentCost {
    LightOperation {
        base: Word,
        units_per_gas: Word,
    },

}
Expand description

Dependent cost is a cost that depends on the number of units.

Variants§

§

LightOperation

When an operation is dependent on the magnitude of its inputs, and the time per unit of input is less than a single no-op operation

Fields

§base: Word

The minimum that this operation can cost.

§units_per_gas: Word

How many elements can be processed with a single gas. The higher the units_per_gas, the less additional cost you will incur for a given number of units, because you need more units to increase the total cost. This must be nonzero.

§

HeavyOperation

When an operation is dependent on the magnitude of its inputs, and the time per unit of input is greater than a single no-op operation

Fields

§base: Word

The minimum that this operation can cost.

§gas_per_unit: Word

How much gas is required to process a single unit.
