findImportedModule :: HscEnv -> ModuleName -> Maybe FastString -> IO FindResultSource

Locate a module that was imported by the user. We have the module's name, and possibly a package name. Without a package name, this function will use the search path and the known exposed packages to find the module, if a package is specified then only that package is searched for the module.

findExactModule :: HscEnv -> Module -> IO FindResultSource

Locate a specific Module. The purpose of this function is to create a ModLocation for a given Module, that is to find out where the files associated with this module live. It is used when reading the interface for a module mentioned by another interface, for example (a system import).

findHomeModule :: HscEnv -> ModuleName -> IO FindResultSource

Search for a module in the home package only.
