Enum OperatorCostStrategy 

pub enum OperatorCostStrategy {
    Table(Box<OperatorCost>),
    Default,
}

The cost of each operator.

Note: a more dynamic approach (e.g. a user-supplied callback) can be added as a variant in the future if needed.

Variants

Table(Box<OperatorCost>)

A table of operator costs.

Default

Each cost defaults to 1 fuel unit, except Nop, Drop and a few control flow operators.

Implementations

impl OperatorCostStrategy

pub fn table(cost: OperatorCost) -> Self

Create a new operator cost strategy with a table of costs.

pub fn cost(&self, op: &Operator<'_>) -> i64

Get the cost of an operator.

Trait Implementations

impl Clone for OperatorCostStrategy

fn clone(&self) -> OperatorCostStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperatorCostStrategy

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

Formats the value using the given formatter.

impl Default for OperatorCostStrategy

fn default() -> OperatorCostStrategy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OperatorCostStrategy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for OperatorCostStrategy

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 OperatorCostStrategy

fn eq(&self, other: &OperatorCostStrategy) -> 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 OperatorCostStrategy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
