Struct ReturnStmt 

pub struct ReturnStmt { /* private fields */ }

Implementations

impl ReturnStmt

pub fn value(&self) -> Option<Expr>

Returns the value expression, if any.

A bare return has no child expression node; return expr always wraps the expression in a typed node (the parser calls expression()).

pub fn has_value(&self) -> bool

Returns true if the return has a value expression.

Trait Implementations

impl AstNode for ReturnStmt

fn can_cast(kind: SyntaxKind) -> bool

Returns true if a node with the given kind can be cast to Self.

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

Try to cast a generic SyntaxNode into this typed wrapper.

fn syntax(&self) -> &SyntaxNode

Access the underlying SyntaxNode.

impl Clone for ReturnStmt

fn clone(&self) -> ReturnStmt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReturnStmt

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

Formats the value using the given formatter.

impl Display for ReturnStmt

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

Formats the value using the given formatter.

impl Eq for ReturnStmt

impl Hash for ReturnStmt

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 ReturnStmt

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