Enum LogicalType

Source

pub enum LogicalType {
    Entity,
    TruthValue,
    Property,
    Quantifier,
}

Expand description

Montague semantic types for compositional interpretation.

These types classify expressions according to their denotation in a model-theoretic semantics, following Montague’s “Universal Grammar”.

Variants§

§

Entity

Type e: Individuals (entities) like “John” or “the ball”.

§

TruthValue

Type t: Truth values (propositions) like “John runs”.

§

Property

Type <e,t>: Properties (one-place predicates) like “is a unicorn”.

§

Quantifier

Type <<e,t>,t>: Generalized quantifiers like “every man” or “a woman”.

impl Clone for LogicalType

Source §

fn clone(&self) -> LogicalType

Returns a duplicate of the value. Read more

1.0.0 (const: unstable) · Source§

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

Performs copy-assignment from source. Read more

impl Debug for LogicalType

Source §

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

Formats the value using the given formatter. Read more

Source §

impl PartialEq for LogicalType

Source §

fn eq(&self, other: &LogicalType) -> bool

Tests for self and other values to be equal, and is used by ==.

1.0.0 (const: unstable) · Source§

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Source §

unsafe fn clone_to_uninit(&self, dest: *mut u8)

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

§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

§

impl<T> DowncastSync for T
where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
