Struct rustc_ast::tokenstream::LazyTokenStream
source · [−]pub struct LazyTokenStream(Lrc<Box<dyn CreateTokenStream>>);
Expand description
A lazy version of TokenStream
, which defers creation
of an actual TokenStream
until it is needed.
Box
is here only to reduce the structure size.

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
