At the moment
libsyntax always loads source code from the file system when it imports a module. All source code loading seems to go through
It should be easy add a
ParseSess to which
file_to_filemap() delegates the mapping from file name to source string. How the
CodebaseAccessor then provides the source string could be pretty much anything.
One use case for this would be IDE’s which want to use
librustc but want to provide it with source file version’s which don’t exist on disk yet.
I hope to get around to implementing this some time but I’d like to get some feedback on the idea first. Also, I haven’t investigated how this would interact with macros loaded from plugins. If someone knows anything about this, I’d be very interested in hearing about it.
