Enum Weight 

pub enum Weight<T>
where
    T: Zero<T> + Add<Output = T> + Sub<Output = T> + PartialEq + PartialOrd + Copy + Display,
{
    Unit(T),
    Infinity,
    NaN,
}

Generic implementation of weight with any units that implement std::ops::Add and std::ops::Sub. This type wraps the unit in a system with an infinity point and a “not a number” point used by the algorithms.

Implements WeightUnit and Zero.

Example

use core_cbc_casper::util::weight::Weight::{self, *};

assert_eq!(Unit(2), Unit(1) + Unit(1));
assert_eq!(Infinity, Unit(1) + Infinity);
assert_eq!(Weight::<u32>::NaN.to_string(), (Unit(1) + NaN).to_string());

Variants

Unit(T)

Infinity

NaN

Trait Implementations

impl<T> Add for Weight<T>

where T: Zero<T> + Add<Output = T> + Sub<Output = T> + PartialEq + PartialOrd + Copy + Display,

type Output = Weight<T>

The resulting type after applying the + operator.

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

Performs the + operation.

impl<T> AddAssign for Weight<T>

where T: Zero<T> + Add<Output = T> + Sub<Output = T> + PartialEq + PartialOrd + Copy + Display + Clone,

fn clone(&self) -> Weight<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Weight<T>

where T: Zero<T> + Add<Output = T> + Sub<Output = T> + PartialEq + PartialOrd + Copy + Display,

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

Formats the value using the given formatter.

impl<T> Display for Weight<T>

where T: Zero<T> + Add<Output = T> + Sub<Output = T> + PartialEq + PartialOrd + Copy + Display,

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

impl<T> PartialEq for Weight<T>

where T: Zero<T> + Add<Output = T> + Sub<Output = T> + PartialEq + PartialOrd + Copy + Display,

fn eq(&self, other: &Self) -> 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.

where T: Zero<T> + Add<Output = T> + Sub<Output = T> + PartialEq + PartialOrd + Copy + Display,

fn partial_cmp(&self, other: &Self) -> 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<T> Sub for Weight<T>

where T: Zero<T> + Add<Output = T> + Sub<Output = T> + PartialEq + PartialOrd + Copy + Display,

type Output = Weight<T>

The resulting type after applying the - operator.

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

Performs the - operation.

impl<T> SubAssign for Weight<T>
