//! Safe wrapper around the LLVM C API.
//!
//! References returned from the LLVM API are tied to the `'llvm` lifetime which is bound to the
//! context where the objects are created in.
//! We do not offer wrappers to remove or delete any objects in the context and therefore all the
//! references will be valid for the liftime of the context.
//!
//! For the scope of this tutorial we mainly use assertions to validate the results from the LLVM
//! API calls.
