   3 // This file tests the source-partitioning behavior of rustdoc.
   4 // Each test contains some code that should be put into the generated
   5 // `fn main` and some attributes should be left outside (except the first
   6 // one, which has no attributes).
   7 // If the #![recursion_limit] attribute is incorrectly left inside,
   8 // then the tests will fail because the macro recurses 128 times.
