Struct CoreUniversalVar

pub struct CoreUniversalVar<L: Language> {
    pub kind: CoreKind<L>,
    pub var_index: VarIndex,
}

A universal variable is a dummy variable about which nothing is known except that which we see in the environment. When we want to prove something is true for all T (∀T), we replace T with a universal variable.

Fields

kind: CoreKind<L>

var_index: VarIndex

Trait Implementations

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<L: Language> Debug for CoreUniversalVar<L>

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

Formats the value using the given formatter.

impl<L: Language> DowncastTo<CoreUniversalVar<L>> for CoreUniversalVar<L>

fn downcast_to(&self) -> Option<CoreUniversalVar<L>>

impl<L: Language> DowncastTo<CoreUniversalVar<L>> for CoreVariable<L>

fn downcast_to(&self) -> Option<CoreUniversalVar<L>>

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

fn cmp(&self, other: &CoreUniversalVar<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 CoreUniversalVar<L>

fn eq(&self, other: &CoreUniversalVar<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 CoreUniversalVar<L>

fn partial_cmp(&self, other: &CoreUniversalVar<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.
