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

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