//! Forces rustc to link every module crate's rlib into the test binary.
//!
//! The facade itself only references the modules through `extern "C"`
//! imports (see src/bridge), so rustc would otherwise drop the
//! dev-dependency rlibs from the link and leave the imports undefined.
//! Referencing one exported item per crate makes the linker pull the
//! crate's objects in; the `#[no_mangle]` exports then satisfy the
//! bridge imports.

/// Smoke-test that every module crate links: each referenced export is
/// called once and must return a sane value or a handle.
