Trait Implementations

impl<L: Clone + Language> Clone for CoreVarSubstitution<L>

fn clone(&self) -> CoreVarSubstitution<L>

Returns a duplicate of the value.

Performs copy-assignment from source.

impl<L: Debug + Language> Debug for CoreVarSubstitution<L>

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

Formats the value using the given formatter.

impl<L: Default + Language> Default for CoreVarSubstitution<L>

fn default() -> CoreVarSubstitution<L>

Returns the “default value” for a type.

impl<L, A, B> Extend<(A, B)> for CoreVarSubstitution<L>

where L: Language, A: Upcast<CoreVariable<L>>, B: Upcast<CoreVariable<L>>,

fn extend<T: IntoIterator<Item = (A, B)>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

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

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

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

Reserves capacity in a collection for the given number of additional elements.

impl<L, A, B> FromIterator<(A, B)> for CoreVarSubstitution<L>

where L: Language, A: Upcast<CoreVariable<L>>, B: Upcast<CoreVariable<L>>,

fn from_iter<T: IntoIterator<Item = (A, B)>>(iter: T) -> Self

Creates a value from an iterator.

impl<L: Hash + Language> Hash for CoreVarSubstitution<L>

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<L: Ord + Language> Ord for CoreVarSubstitution<L>

fn cmp(&self, other: &CoreVarSubstitution<L>) -> 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<L: PartialEq + Language> PartialEq for CoreVarSubstitution<L>

fn eq(&self, other: &CoreVarSubstitution<L>) -> 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<L: PartialOrd + Language> PartialOrd for CoreVarSubstitution<L>

fn partial_cmp(&self, other: &CoreVarSubstitution<L>) -> 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.
