Struct outils::types::EmptyWeight

pub struct EmptyWeight;

Unit-like (i.e. zero-sized) struct that can be used as an WeightType.

Trait Implementations

type Output = EmptyWeight

The resulting type after applying the + operator.

fn add(self, _other: EmptyWeight) -> EmptyWeight

Performs the + operation.

impl AddAssign<EmptyWeight> for EmptyWeight

fn add_assign(&mut self, _other: EmptyWeight)

Performs the += operation.

impl Clone for EmptyWeight

fn clone(&self) -> EmptyWeight

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for EmptyWeight

impl Debug for EmptyWeight

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

Formats the value using the given formatter.

impl Default for EmptyWeight

fn default() -> Self

Returns the "default value" for a type.

impl Eq for EmptyWeight

impl Hash for EmptyWeight

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, 

Feeds a slice of this type into the given Hasher.

impl Ord for EmptyWeight

fn cmp(&self, other: &EmptyWeight) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<EmptyWeight> for EmptyWeight

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<EmptyWeight> for EmptyWeight

fn partial_cmp(&self, other: &EmptyWeight) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
