Struct AstPtr 

pub struct AstPtr<N>
where
    N: AstNode,
{ /* private fields */ }

Like SyntaxNodePtr, but remembers the type of node.

Implementations

impl<N> AstPtr<N>

where N: AstNode,

pub fn new(node: &N) -> AstPtr<N>

Returns an AstPtr for the node.

pub fn to_node(&self, root: &SyntaxNode<<N as AstNode>::Language>) -> N

Like Self::try_to_node but panics on failure.

pub fn try_to_node( &self, root: &SyntaxNode<<N as AstNode>::Language>, ) -> Option<N>

Given the root node containing the node n that self is a pointer to, returns n if possible. See SyntaxNodePtr::try_to_node.

pub fn syntax_node_ptr(&self) -> SyntaxNodePtr<<N as AstNode>::Language>

Returns the underlying SyntaxNodePtr.

pub fn cast<U>(self) -> Option<AstPtr<U>>

where U: AstNode<Language = <N as AstNode>::Language>,

Casts this to an AstPtr to the given node type if possible.
