newField :: Field Source #

Create a value of Field 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:doubleValue:Field', field_doubleValue - A value of the double data type.

$sel:stringValue:Field', field_stringValue - A value of the string data type.

$sel:longValue:Field', field_longValue - A value of the long data type.

$sel:booleanValue:Field', field_booleanValue - A value of the Boolean data type.

$sel:blobValue:Field', field_blobValue - A value of the BLOB data type.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

$sel:isNull:Field', field_isNull - A value that indicates whether the data is NULL.

field_doubleValue :: Lens' Field (Maybe Double) Source #

A value of the double data type.

field_stringValue :: Lens' Field (Maybe Text) Source #

A value of the string data type.

field_longValue :: Lens' Field (Maybe Integer) Source #

A value of the long data type.

field_booleanValue :: Lens' Field (Maybe Bool) Source #

A value of the Boolean data type.

field_blobValue :: Lens' Field (Maybe ByteString) Source #

A value of the BLOB data type.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

field_isNull :: Lens' Field (Maybe Bool) Source #

A value that indicates whether the data is NULL.
