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

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.
