Enum WitnessTerm 

pub enum WitnessTerm {
    Elem {
        element: Element,
    },
    Const {
        constant: C,
    },
    App {
        function: F,
        terms: Vec<WitnessTerm>,
    },
}

Implements WitnessTermTrait, with Element as the ElementType and serves as witness terms for Model.

Variants

Elem

Wraps an instance of Element, witnessing itself.

Fields

element: Element

Const

Wraps an instance of C as a witness term.

Fields

constant: C

App

Corresponds to a composite witness term, made by applying an instance of F to a list of witness terms.

Fields

function: F

terms: Vec<WitnessTerm>

Implementations

impl WitnessTerm

pub fn witness(term: &Term, lookup: &impl Fn(&V) -> Element) -> WitnessTerm

Given a term and an assignment function assign from variables of the term to elements of a Model, constructs a WitnessTerm.

Trait Implementations

impl Clone for WitnessTerm

fn clone(&self) -> WitnessTerm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Display for WitnessTerm

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

Formats the value using the given formatter.

impl FApp for WitnessTerm

fn apply(function: F, terms: Vec<Self>) -> Self

Builds a composite term by applying function on terms as arguments.

impl From<C> for WitnessTerm

fn from(constant: C) -> Self

Converts to this type from the input type.

impl From<Element> for WitnessTerm

fn from(element: Element) -> Self

Converts to this type from the input type.

impl Hash for WitnessTerm

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 Ord for WitnessTerm

fn cmp(&self, other: &WitnessTerm) -> 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 WitnessTerm

fn eq(&self, other: &WitnessTerm) -> 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 WitnessTerm

fn partial_cmp(&self, other: &WitnessTerm) -> 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 WitnessTermTrait for WitnessTerm

type ElementType = Element

Is the type of elements that are witnessed by the witness term.

fn equals(self, rhs: Self) -> Observation<Self>

Returns an equational Observation between the receiver and the given witness term.

impl Eq for WitnessTerm
