Struct ascent_base::Dual

pub struct Dual<T>(pub T);

A wrapper that swaps (<= and >=), (meet and join), and (top and bottom) for BoundedLattices.

Example

assert!(Dual(2) < Dual(1));

    T: BoundedLattice,
    Dual<T>: Lattice, 

fn top() -> Self

fn bottom() -> Self

impl<T: Clone> Clone for Dual<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Dual<T>

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

Formats the value using the given formatter.

impl<T> Deref for Dual<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T: Display> Display for Dual<T>

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

Formats the value using the given formatter.

impl<T: Hash> Hash for Dual<T>

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<T> Lattice for Dual<T> where
    T: Lattice, 

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

the greatest lower bound of two elements. meet(x, y) is the largest value x s.t. z <= x and z <= y

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

The least upper bound of two elements. join(x, y) is the smallest value z s.t. z >= x and z >= y.

fn meet_mut(&mut self, other: Self) -> bool

ensures self is the join of self and other

fn join_mut(&mut self, other: Self) -> bool

ensures self is the meet of self and other.

impl<T> Ord for Dual<T> where
    T: Ord, 

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq<Dual<T>> for Dual<T>

fn eq(&self, other: &Dual<T>) -> bool

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

fn ne(&self, other: &Dual<T>) -> bool

This method tests for !=.

impl<T> PartialOrd<Dual<T>> for Dual<T> where
    T: PartialOrd, 

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

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

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

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

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

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

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

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