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