Implementations
sourceimpl Stmt
impl Stmt
pub fn has_trailing_semicolon(&self) -> bool
sourcepub fn add_trailing_semicolon(self) -> Self
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
LazyTokenStream
. The parser is responsible for calling
CreateTokenStream::add_trailing_semi
when there is actually
a semicolon in the tokenstream.

This is true

attributes. Attributes like #![cfg]
and #![cfg_attr]
are not
considered ‘custom’ attributes. Read more

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.
