Struct SyntaxNode 

pub struct SyntaxNode(/* private fields */);

An opaque, navigable interior node of the CST.

Wraps rowan::SyntaxNode<RonLang>; the inner rowan type is never exposed.

Implementations

impl SyntaxNode

pub fn kind(&self) -> SyntaxKind

This node’s classification.

pub fn text_range(&self) -> TextRange

Absolute byte range spanned by this node (union of descendant tokens).

pub fn text(&self) -> String

The full source text spanned by this node, including trivia, as a string.

pub fn parent(&self) -> Option<SyntaxNode>

Parent node, or None for the root.

pub fn children(&self) -> impl Iterator<Item = SyntaxNode>

Direct child nodes (excluding tokens), in source order.

pub fn children_with_tokens(&self) -> impl Iterator<Item = SyntaxElement>

Direct children (both nodes and tokens), in source order.

pub fn descendant_tokens(&self) -> impl Iterator<Item = SyntaxToken>

Every descendant token (leaves), in source order — the basis for printing.

pub fn first_token_of(&self, kind: SyntaxKind) -> Option<SyntaxToken>

First child token whose kind matches kind, if any.
