Experience with the `define_function` API has shown that returning borrowed slices of `TrapSite` is not ideal: the returned slice represents a borrow on the entire `Module`, which makes calling back into methods taking `&mut self` a bit tricky. To eliminate the problem, let's require the callers of `define_function` to provide `TrapSink` instances. This style of API enables them to control when and how traps are collected, and makes the `object` and `faerie` backends simpler/more efficient by not having to worry about trap collection.
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.ObjectBackend, provided by cranelift-object, which emits native object files.FaerieBackend, provided by cranelift-faerie, which emits native object files.
