The failure crate invents its own traits that don't use std::error::Error (because failure predates certain features added to Error); this prevents using ? on an error from failure in a function using Error. The thiserror crate integrates with the standard Error trait instead.
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.
