Enum ModalOb

pub enum ModalOb {
    Generator(QualifiedName),
    App(Box<Self>, QualifiedName),
    List(List, Vec<Self>),
}

Object in a model of a modal double theory.

Variants

Generator(QualifiedName)

Generating object.

App(Box<Self>, QualifiedName)

Application of a generating object operation.

List(List, Vec<Self>)

List of objects in a list modality.

Implementations

impl ModalOb

pub fn generator(self) -> Option<QualifiedName>

Extracts an object generator or nothing.

pub fn unwrap_generator(self) -> QualifiedName

Unwraps an object generator, or panics.

pub fn collect_product(self, op_id: Option<QualifiedName>) -> Option<Vec<Self>>

Collects application of a product operation into a list of objects.

The intended operation has domain equal to the list modality applied to its codomain, which usually signifies a product of some kind.

Trait Implementations

impl Clone for ModalOb

fn clone(&self) -> ModalOb

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModalOb

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

Formats the value using the given formatter.

impl From<QualifiedName> for ModalOb

fn from(value: QualifiedName) -> Self

Converts to this type from the input type.

impl PartialEq for ModalOb

fn eq(&self, other: &ModalOb) -> 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.
