Struct SyntaxNodePtr 

pub struct SyntaxNodePtr { /* private fields */ }

An untyped lightweight pointer to a syntax node, resolvable against a tree.

Stores SyntaxKind + TextRange — the same data as AstPtr but without a type parameter, so it can point at nodes of heterogeneous kinds.

Implementations

impl SyntaxNodePtr

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

Create a pointer from a live syntax node.

pub fn text_range(&self) -> TextRange

The text range this pointer points to.

pub fn syntax_kind(&self) -> SyntaxKind

The syntax kind of the pointed-to node.

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

Resolve this pointer back to a live syntax node.

Trait Implementations

impl Clone for SyntaxNodePtr

fn clone(&self) -> SyntaxNodePtr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SyntaxNodePtr

impl Debug for SyntaxNodePtr

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

Formats the value using the given formatter.

impl Eq for SyntaxNodePtr

impl<N: AstNode> From<AstPtr<N>> for SyntaxNodePtr

fn from(ptr: AstPtr<N>) -> Self

Converts to this type from the input type.

impl Hash for SyntaxNodePtr

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SyntaxNodePtr

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