Struct NodeMeta 

pub struct NodeMeta {
    pub span: Option<Span>,
}

Metadata attached to every AST node; currently just the source span.

Fields

span: Option<Span>

The node’s source location, or None for hand-built nodes.

Implementations

impl NodeMeta

pub const fn new(span: Option<Span>) -> Self

Wrap an optional Span into a NodeMeta.

Trait Implementations

impl Clone for NodeMeta

fn clone(&self) -> NodeMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeMeta

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

Formats the value using the given formatter.

impl Default for NodeMeta

fn default() -> NodeMeta

Returns the “default value” for a type.

impl Eq for NodeMeta

impl PartialEq for NodeMeta

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