Documentation
Records what things are "available", i.e. in scope
Constructors
| Avail Name | An ordinary identifier in scope |
| 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 #
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 GenAvailInfo
availNames :: AvailInfo -> [Name] Source #
All names made available by the availability information (excluding overloaded selectors)
availNonFldNames :: AvailInfo -> [Name] Source #
Names for non-fields made available by the availability information
availNamesWithSelectors :: AvailInfo -> [Name] Source #
All names made available by the availability information (including overloaded selectors)
availFlds :: AvailInfo -> [FieldLabel] Source #
Fields made available by the availability information
availNamesWithOccs :: AvailInfo -> [(Name, OccName)] Source #
Names made available by the availability information, paired with
the OccName used to refer to each one.
When DuplicateRecordFields is in use, the Name may be the
mangled name of a record selector (e.g. $sel:foo:MkT) while the
OccName will be the label of the field (e.g. foo).
See Note [Representing fields in AvailInfo].
filterAvail :: (Name -> Bool) -> AvailInfo -> [AvailInfo] -> [AvailInfo] Source #
filters an AvailInfo by the given predicate
