Struct Node 

pub struct Node {
    pub kind: NodeKind,
    pub span: Span,
}

A spanned AST node combining a NodeKind with its source Span.

Fields

kind: NodeKind

span: Span

Implementations

impl Node

pub const fn new(kind: NodeKind, span: Span) -> Self

Creates a new node with the given kind and span.

pub const fn empty(kind: NodeKind) -> Self

Creates a node with an empty span (for synthetic or temporary nodes).

pub fn source_text<'a>(&self, source: &'a str) -> &'a str

Extracts the source text for this node from the original source string.

Spans use character indices (matching Token.pos semantics). Returns an empty string for synthetic nodes or invalid spans.

Trait Implementations

impl Clone for Node

fn clone(&self) -> Node

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Node

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

Formats the value using the given formatter.

impl Display for Node

Node delegates Display to its inner NodeKind.

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

Formats the value using the given formatter.

impl PartialEq for Node

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