Struct valkyrie_ast::NullNode

pub struct NullNode {
    pub nil: bool,
    pub span: Range<u32>,
}

null, nil, type of null value

Fields

nil: bool

Whether the collection is empty or does not exist

span: Range<u32>

The range of the node

Implementations

impl NullNode

pub fn as_str(&self) -> &'static str

Returns the string representation of the null value.

Trait Implementations

impl Clone for NullNode

fn clone(&self) -> NullNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NullNode

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

Formats the value using the given formatter.

impl From<NullNode> for ExpressionKind

fn from(o: NullNode) -> Self

Converts to this type from the input type.

impl Hash for NullNode

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 PartialEq for NullNode

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl ValkyrieNode for NullNode

fn get_range(&self) -> Range<usize>

The range of the node

fn get_start(&self) -> usize

Get the start of the node

fn get_end(&self) -> usize

Get the end of the node

impl Eq for NullNode
