type FieldLabelEnv = DFastStringEnv FieldLabel Source #

A map from labels to all the auxiliary information

data FieldLabel Source #

Fields in an algebraic record type; see Note [FieldLabel].

Constructors

FieldLabel
Fields flLabel :: FieldLabelString User-visible label of the field flHasDuplicateRecordFields :: DuplicateRecordFields Was `DuplicateRecordFields` on in the defining module for this datatype? flHasFieldSelector :: FieldSelectors Was `FieldSelectors` enabled in the defining module for this datatype? See Note [NoFieldSelectors] in GHC.Rename.Env flSelector :: Name Record selector function

Binary Name => Binary FieldLabel Source #	We need the `Binary Name` constraint here even though there is an instance defined in GHC.Types.Name, because the we have a SOURCE import, so the instance is not in scope. And the instance cannot be added to Name.hs-boot because GHC.Utils.Binary itself depends on GHC.Types.Name.

fieldSelectorOccName :: FieldLabelString -> OccName -> DuplicateRecordFields -> FieldSelectors -> OccName Source #

Record selector OccNames are built from the underlying field name and the name of the first data constructor of the type, to support duplicate record field names. See Note [Why selector names include data constructors].

fieldLabelPrintableName :: FieldLabel -> Name Source #

Undo the name mangling described in Note [FieldLabel] to produce a Name that has the user-visible OccName (but the selector's unique). This should be used only when generating output, when we want to show the label, but may need to qualify it with a module prefix.

data DuplicateRecordFields Source #

Flag to indicate whether the DuplicateRecordFields extension is enabled.

Constructors

DuplicateRecordFields	Fields may be duplicated in a single module
NoDuplicateRecordFields	Fields must be unique within a module (the default)
