typetype LHsUnit n = Located (HsUnit n)

datadata HsUnit n

Top level unit declaration in a Backpack file.

typetype LHsUnitDecl n = Located (HsUnitDecl n)

datadata HsUnitDecl n

A declaration in a package, e.g. a module or signature definition, or an include.

datadata IncludeDecl n

An include of another unit

IncludeDecl
- idUnitId :: LHsUnitId n
- idModRenaming :: Maybe [LRenaming]
- idSignatureInclude :: Bool
  Is this a dependency signature include? If so, we don't compile this include when we instantiate this unit (as there should not be any modules brought into scope.)

typetype LRenaming = Located Renaming

datadata Renaming

Rename a module from one name to another. The identity renaming means that the module should be brought into scope.
