This crate provides module-level functionality, which allow multiple functions and data to be emitted with Cranelift and then linked together.

This crate is structured as an optional layer on top of cranelift-codegen. It provides additional functionality, such as linking, however users that require greater flexibility don't need to use it.

A Module is a collection of functions and data objects that are linked together. Backend is a trait that defines an interface for backends that compile modules into various forms. Most users will use one of the following Backend implementations:

• SimpleJITBackend, provided by cranelift-simplejit, which JITs code to memory for direct execution.
• FaerieBackend, provided by cranelift-faerie, which emits native object files.
