Struct rustc_ast::ast::Stmt

pub struct Stmt {
    pub id: NodeId,
    pub kind: StmtKind,
    pub span: Span,
}

A statement. No attrs or tokens fields because each StmtKind variant contains an AST node with those fields. (Except for StmtKind::Empty, which never has attrs or tokens)

Fields

id: NodeId

kind: StmtKind

span: Span

Implementations

impl Stmt

pub fn has_trailing_semicolon(&self) -> bool

pub fn add_trailing_semicolon(self) -> Self

Converts a parsed Stmt to a Stmt with a trailing semicolon.

This only modifies the parsed AST struct, not the attached LazyAttrTokenStream. The parser is responsible for calling ToAttrTokenStream::add_trailing_semi when there is actually a semicolon in the tokenstream.

pub fn is_item(&self) -> bool

pub fn is_expr(&self) -> bool

Trait Implementations

impl !AstDeref for Stmt

type Target

fn ast_deref(&self) -> &Self::Target

fn ast_deref_mut(&mut self) -> &mut Self::Target

impl Clone for Stmt

fn clone(&self) -> Stmt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Stmt

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for Stmt

fn decode(__decoder: &mut __D) -> Self

impl DummyAstNode for Stmt

fn dummy() -> Self

impl<__E: SpanEncoder> Encodable<__E> for Stmt

fn encode(&self, __encoder: &mut __E)

impl HasAttrs for Stmt

const SUPPORTS_CUSTOM_INNER_ATTRS: bool = true

This is true if this HasAttrs might support ‘custom’ (proc-macro) inner attributes. Attributes like #![cfg] and #![cfg_attr] are not considered ‘custom’ attributes.

fn attrs(&self) -> &[Attribute]

fn visit_attrs(&mut self, f: impl FnOnce(&mut AttrVec))

impl HasNodeId for Stmt

fn node_id(&self) -> NodeId

fn node_id_mut(&mut self) -> &mut NodeId

impl HasTokens for Stmt

fn tokens(&self) -> Option<&LazyAttrTokenStream>

fn tokens_mut(&mut self) -> Option<&mut Option<LazyAttrTokenStream>>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
