Struct SyntaxNode 

pub struct SyntaxNode<'a> { /* private fields */ }

A borrowed handle to one node in a SyntaxTree.

Implementations

impl<'a> SyntaxNode<'a>

pub fn id(self) -> NodeId

pub fn tree(self) -> &'a SyntaxTree

The tree this node belongs to.

Needed to resolve the NodeIds handed out by Self::children, which is how a caller walks nodes and tokens together in source order.

pub fn kind(self) -> SyntaxKind

pub fn range(self) -> TextRange

pub fn text(self) -> &'a str

The exact source text this node covers, trivia included.

pub fn children(self) -> impl Iterator<Item = Element> + 'a

Direct children, nodes and tokens interleaved in source order.

pub fn child_nodes(self) -> impl Iterator<Item = SyntaxNode<'a>> + 'a

Direct child nodes, skipping tokens.

pub fn child_tokens(self) -> impl Iterator<Item = Token> + 'a

Direct child tokens, skipping nodes.

pub fn child_node_of(self, kind: SyntaxKind) -> Option<SyntaxNode<'a>>

The first direct child node of the given kind.

pub fn child_token_of(self, kind: SyntaxKind) -> Option<Token>

The first direct child token of the given kind.

pub fn descendants(self) -> Descendants<'a>

Every node in this subtree, parents before children.

Trait Implementations

fn clone(&self) -> SyntaxNode<'a>

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

Performs copy-assignment from source.

impl<'a> Copy for SyntaxNode<'a>

impl<'a> Debug for SyntaxNode<'a>

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

Formats the value using the given formatter.
