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)
