Enum NodeValue 

pub enum NodeValue {
    Hole(Option<Identifier>),
    Primitive(PrimitiveValue),
    Array(NodeArray),
    Map(NodeMap),
    Tuple(NodeTuple),
}

Variants

Hole(Option<Identifier>)

A hole represents an uninitialized or placeholder value. Optionally includes a label for identification (e.g., !todo, !wip).

Primitive(PrimitiveValue)

Array(NodeArray)

Map(NodeMap)

Tuple(NodeTuple)

Implementations

impl NodeValue

pub fn hole() -> Self

Creates an anonymous hole (no label).

pub fn labeled_hole(label: Identifier) -> Self

Creates a labeled hole.

pub fn is_hole(&self) -> bool

Returns true if this is a hole (labeled or anonymous).

pub fn empty_map() -> Self

pub fn empty_array() -> Self

pub fn empty_tuple() -> Self

pub fn value_kind(&self) -> Option<ValueKind>

Trait Implementations

impl Clone for NodeValue

fn clone(&self) -> NodeValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeValue

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

Formats the value using the given formatter.

impl From<PrimitiveValue> for NodeValue

fn from(p: PrimitiveValue) -> Self

Converts to this type from the input type.

impl PartialEq for NodeValue

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