Module logging 

Plumbing for using the log crate across FFI-boundaries.

By setting up a chain from ForwardLogger => LogTarget => Log, a dynamically loaded library can effectively log to the calling library’s logging implementation.

Usage

• Set up logging as usual
• Construct a StaticLogTarget in the same library
• Pass the LogTarget through FFI
• Register a ForwardLogger in the dynamic library
• Use the log crate as usual

Note: The max logging level is only set once, when the ForwardLogger is registered.
