 (require scheme/unit-exptime)

The scheme/unit-exptime library provides procedures that are intended for use by macro transformers. In particular, the library is typically imported using for-syntax into a module that defines macro with define-syntax.

(unit-static-signatures unit-identifier 
  err-syntax) 
  
(list/c (cons/c (or/c symbol? #f)
                identifier?))
(list/c (cons/c (or/c symbol? #f)
                identifier?))
  unit-identifier : identifier?
  err-syntax : syntax?
If unit-identifier is bound to static unit information via define-unit (or other such forms), the result is two values. The first value is for the unit’s imports, and the second is for the unit’s exports. Each result value is a list, where each list element pairs a symbol or #f with an identifier. The symbol or #f indicates the import’s or export’s tag (where #f indicates no tag), and the identifier indicates the binding of the corresponding signature.

If unit-identifier is not bound to static unit information, then the exn:fail:syntax exception is raised. In that case, the given err-syntax argument is used as the source of the error, where unit-identifer is used as the detail source location.

(signature-members sig-identifier    
  err-syntax)  
(or/c identifier? #f)
(listof identifier?)
(listof identifier?)
(listof identifier?)
  sig-identifier : identifier?
  err-syntax : syntax?
If sig-identifier is bound to static unit information via define-signature (or other such forms), the result is four values:

If sig-identifier is not bound to a signature, then the exn:fail:syntax exception is raised. In that case, the given err-syntax argument is used as the source of the error, where sig-identifier is used as the detail source location.
