error: an inner attribute is not permitted in this context

LL | #![lang = "foo"]
   | ^^^^^^^^^^^^^^^^
LL | fn foo() {}
   | ----------- the inner attribute doesn't annotate this function
   |
   = note: inner attributes, like `#![no_std]`, annotate the item enclosing them, and are usually found at the beginning of source files
help: to annotate the function, change the attribute from inner to outer style

LL - #![lang = "foo"]
LL + #[lang = "foo"]
