Struct NodePtr 

pub struct NodePtr { /* private fields */ }

A location-based handle to a syntax node: its SyntaxKind plus its text range. Cheap (Copy), serializable, and resolvable to a live SyntaxNode via NodePtr::try_to_node.

Implementations

impl NodePtr

pub fn from_node(node: &SyntaxNode) -> Self

Capture a handle to node.

pub fn kind(&self) -> SyntaxKind

The kind of node this points to.

pub fn text_range(&self) -> TextRange

The text range this points to.

pub fn with_range(self, range: TextRange) -> Self

Return a copy pointing at range, keeping the kind. Used after mapping the range across an edit.

pub fn try_to_node(&self, root: &SyntaxNode) -> Option<SyntaxNode>

Resolve this handle to a node in root, which must be a root built from the same text the handle was taken against (or a range already mapped onto that text). Returns None if root is not a root, the range falls outside it, or no node of the stored kind spans exactly the stored range.
