1. variantTypeStringIsValid :: (HasCallStack, MonadIO m) => Text -> m Bool

   gi-glib	GI.GLib.Structs.VariantType

   Checks if typeString is a valid GVariant type string. This call is equivalent to calling variantTypeStringScan and confirming that the following character is a nul terminator.

2. clearTokenValueVIdentifier :: MonadIO m => TokenValue -> m ()

   gi-glib	GI.GLib.Unions.TokenValue

   Set the value of the “v_identifier” field to Nothing. When overloading is enabled, this is equivalent to

   clear #vIdentifier
   

3. getTokenValueVIdentifier :: MonadIO m => TokenValue -> m (Maybe Text)

   gi-glib	GI.GLib.Unions.TokenValue

   Get the value of the “v_identifier” field. When overloading is enabled, this is equivalent to

   get tokenValue #vIdentifier
   

4. setTokenValueVIdentifier :: MonadIO m => TokenValue -> CString -> m ()

   gi-glib	GI.GLib.Unions.TokenValue

   Set the value of the “v_identifier” field. When overloading is enabled, this is equivalent to

   set tokenValue [ #vIdentifier := value ]
   

5. type C_ParamSpecTypeInfoValueValidateFieldCallback = Ptr GParamSpec -> Ptr GValue -> IO CInt

   gi-gobject	GI.GObject.Callbacks

   Type for the callback on the (unwrapped) C side.

6. type ParamSpecTypeInfoValueValidateFieldCallback = GParamSpec -> GValue -> IO Bool

   gi-gobject	GI.GObject.Callbacks

   No description available in the introspection data.

7. dynamic_ParamSpecTypeInfoValueValidateFieldCallback :: (HasCallStack, MonadIO m) => FunPtr C_ParamSpecTypeInfoValueValidateFieldCallback -> GParamSpec -> GValue -> m Bool

   gi-gobject	GI.GObject.Callbacks

   Given a pointer to a foreign C function, wrap it into a function callable from Haskell.

8. genClosure_ParamSpecTypeInfoValueValidateFieldCallback :: MonadIO m => ParamSpecTypeInfoValueValidateFieldCallback -> m (GClosure C_ParamSpecTypeInfoValueValidateFieldCallback)

   gi-gobject	GI.GObject.Callbacks

   Wrap the callback into a GClosure.

9. mk_ParamSpecTypeInfoValueValidateFieldCallback :: C_ParamSpecTypeInfoValueValidateFieldCallback -> IO (FunPtr C_ParamSpecTypeInfoValueValidateFieldCallback)

   gi-gobject	GI.GObject.Callbacks

   Generate a function pointer callable from C code, from a C_ParamSpecTypeInfoValueValidateFieldCallback.

10. noParamSpecTypeInfoValueValidateFieldCallback :: Maybe ParamSpecTypeInfoValueValidateFieldCallback

    gi-gobject	GI.GObject.Callbacks

    A convenience synonym for Nothing :: Maybe ParamSpecTypeInfoValueValidateFieldCallback.
