Implementations§

source§

impl Stmt

source

pub fn has_trailing_semicolon(&self) -> bool

source

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
