Implementations

impl ConstCost

pub const fn cost(&self) -> i32

pub const fn steps(value: i32) -> Self

pub const fn holes(value: i32) -> Self

pub const fn range_checks(value: i32) -> Self

impl ConstCost

pub const fn add(self, rhs: Self) -> Self

Trait Implementations

impl Add for ConstCost

Adds two ConstCost instances.

type Output = ConstCost

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for ConstCost

fn clone(&self) -> ConstCost

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CostTypeTrait for ConstCost

fn min2(value1: &Self, value2: &Self) -> Self

Computes the minimum of the given two value (for each token type).

fn max(values: impl Iterator<Item = Self>) -> Self

Computes the maximum of the given value (for each token type).

fn rectify(value: &Self) -> Self

For each token type, returns the value if it is non-negative and 0 otherwise.

impl Debug for ConstCost

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

Formats the value using the given formatter.

impl Default for ConstCost

fn default() -> ConstCost

Returns the “default value” for a type.

impl From<ConstCost> for BranchCost

Converts ConstCost into BranchCost.

fn from(value: ConstCost) -> Self

Converts to this type from the input type.

impl PartialEq for ConstCost

fn eq(&self, other: &ConstCost) -> 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 PostCostTypeEx for ConstCost

fn from_const_cost(const_cost: &ConstCost) -> Self

Constructor from ConstCost.

fn to_full_cost_map(self) -> OrderedHashMap<CostTokenType, i64>

See SpecificCostContextTrait::to_full_cost_map.

impl Sub for ConstCost

Subtracts two ConstCost instances.

type Output = ConstCost

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl Copy for ConstCost

impl Eq for ConstCost

impl StructuralPartialEq for ConstCost
