Enum DependentCost

pub enum DependentCost {
    LightOperation {
        base: Word,
        units_per_gas: Word,
    },
    HeavyOperation {
        base: Word,
        gas_per_unit: Word,
    },
}

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.

Implementations

impl DependentCost

pub fn free() -> Self

Create costs that make operations free.

pub fn unit() -> Self

pub fn from_units_per_gas(base: Word, units_per_gas: Word) -> Self

pub fn from_gas_per_unit(base: Word, gas_per_unit: Word) -> Self

pub fn base(&self) -> Word

pub fn set_base(&mut self, value: Word)

pub fn resolve(&self, units: Word) -> Word

pub fn resolve_without_base(&self, units: Word) -> Word

Trait Implementations

impl Clone for DependentCost

fn clone(&self) -> DependentCost

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DependentCost

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DependentCost

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for DependentCost

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DependentCost

fn eq(&self, other: &DependentCost) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DependentCost

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
