Documentation
Records what things are "available", i.e. in scope
Constructors
| Avail Name | An ordinary identifier in scope, or a field label without a parent type (see Note [Representing pattern synonym fields in AvailInfo]). |
| AvailTC | A type or class in scope The AvailTC Invariant: If the type or class is itself to be in scope, it must be first in this list. Thus, typically: AvailTC Eq [Eq, ==, \/=] |

availsToNameSet :: [AvailInfo] -> NameSet Source #
availExportsDecl :: AvailInfo -> Bool Source #
Does this AvailInfo export the parent decl? This depends on the
invariant that the parent is first if it appears at all.
availName :: AvailInfo -> Name Source #
Just the main name made available, i.e. not the available pieces
of type or class brought into scope by the AvailInfo
availNames :: AvailInfo -> [Name] Source #
Names and fields made available by the availability information.
availSubordinateNames :: AvailInfo -> [Name] Source #
Names and fields made available by the availability information, other than the main decl itself.
filterAvail :: (Name -> Bool) -> AvailInfo -> [AvailInfo] -> [AvailInfo] Source #
filters an AvailInfo by the given predicate
