Arguments

:: Text	`$sel:value:NullValueField'`
-> Datatype	`$sel:datatype:NullValueField'`
-> NullValueField

Create a value of NullValueField with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:value:NullValueField', nullValueField_value - The value of the null placeholder.

$sel:datatype:NullValueField', nullValueField_datatype - The datatype of the value.

nullValueField_value :: Lens' NullValueField Text Source #

The value of the null placeholder.

nullValueField_datatype :: Lens' NullValueField Datatype Source #

The datatype of the value.
