The current interface of `cranelift-module` requires consumers who want
to be informed about traps to discover that information through
`Module::Product`, which is backend-specific. Since it's advantageous
to manipulate this information in a backend-agnostic way, this patch
changes `Module::define_function{,_bytes}` to return information about
the traps contained in the function being defined.
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.
