Struct TypeNode 

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

Implementations

impl TypeNode

pub fn cast(node: SyntaxNode) -> Option<Self>

Wrap node if its SyntaxKind matches; otherwise return None. O(1) — just a kind check.

pub fn syntax(&self) -> &SyntaxNode

Borrow the underlying SyntaxNode. Useful for downstream traversals that want CST-level access.

pub fn text(&self) -> String

Verbatim source text spanned by this node, including trivia. Cheap on rowan (it walks the green tree).

impl TypeNode

pub fn path_text(&self) -> Vec<String>

Path segments — Foo / Foo.Bar / "foo".Bar. Returns the raw text of each IDENT / STRING token preceding the first generic / ?.

pub fn generics(&self) -> impl Iterator<Item = TypeNode> + '_

Direct-child TYPE_NODEs nested inside this one’s generic argument list.

pub fn is_optional(&self) -> bool

Foo? — true when the trailing ? is present.

Trait Implementations

impl Clone for TypeNode

fn clone(&self) -> TypeNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeNode

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

Formats the value using the given formatter.

impl Eq for TypeNode

impl Hash for TypeNode

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 TypeNode

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