A vote weight.

Tuple Fields

Implementations

impl Weight

pub fn checked_add(self, rhs: Weight) -> Option<Weight>

Checked addition. Returns None if overflow occurred.

pub fn saturating_add(self, rhs: Weight) -> Weight

Saturating addition. Returns Weight(u64::MAX) if overflow would occur.

pub fn saturating_sub(self, rhs: Weight) -> Weight

Saturating subtraction. Returns Weight(0) if underflow would occur.

pub fn is_zero(self) -> bool

Returns true if this weight is zero.

Trait Implementations

impl Add for Weight

type Output = Weight

The resulting type after applying the + operator.

fn add(self, rhs: Weight) -> Weight

Performs the + operation.

impl AddAssign for Weight

fn add_assign(&mut self, rhs: Weight)

Performs the += operation.

impl Clone for Weight

fn clone(&self) -> Weight

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSize for Weight

const IS_DYNAMIC: bool = false

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

fn estimate_detailed_heap_size(&self) -> MemUsageNode

Create a tree of memory estimations.

impl Debug for Weight

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

Formats the value using the given formatter.

impl Default for Weight

fn default() -> Weight

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Weight

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Div<u64> for Weight

type Output = Weight

The resulting type after applying the / operator.

fn div(self, rhs: u64) -> Self

Performs the / operation.

impl From<Weight> for u128

fn from(Weight: Weight) -> u128

Converts to this type from the input type.

impl From<u64> for Weight

fn from(original: u64) -> Weight

Converts to this type from the input type.

impl Mul<u64> for Weight

type Output = Weight

The resulting type after applying the * operator.

fn mul(self, rhs: u64) -> Self

Performs the * operation.

impl Ord for Weight

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Weight

fn eq(&self, other: &Weight) -> 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 PartialOrd for Weight

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Weight

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sub for Weight

type Output = Weight

The resulting type after applying the - operator.

fn sub(self, rhs: Weight) -> Weight

Performs the - operation.

impl SubAssign for Weight

fn sub_assign(&mut self, rhs: Weight)

Performs the -= operation.

impl<'a> Sum<&'a Weight> for Weight

fn sum<I: Iterator<Item = &'a Weight>>(iter: I) -> Self

Takes an iterator and generates Self from the elements by “summing up” the items.

impl Sum for Weight

fn sum<I: Iterator<Item = Self>>(iter: I) -> Self

Takes an iterator and generates Self from the elements by “summing up” the items.

impl Copy for Weight
