Enum ModalNode

pub enum ModalNode {
    Basic(ModeApp<ModalOp>),
    Unit(ModeApp<ModalOp>),
    Composite(Path<ModalObType, ModalMorType>),
}

A node in a morphism operation of a modal double theory.

A generic morphism operation in a modal double theory is a double tree built out of these nodes.

Variants

Basic(ModeApp<ModalOp>)

Basic morphism operation.

Unit(ModeApp<ModalOp>)

Unit cell on a basic object operation.

Composite(Path<ModalObType, ModalMorType>)

Cell witnessing a composite.

By assumption, modalities preserve all composites in the theory.

Trait Implementations

impl Clone for ModalNode

fn clone(&self) -> ModalNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModalNode

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

Formats the value using the given formatter.

impl From<ModeApp<ModalOp>> for ModalNode

fn from(value: ModeApp<ModalOp>) -> Self

Converts to this type from the input type.

impl PartialEq for ModalNode

fn eq(&self, other: &ModalNode) -> 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 Eq for ModalNode
