newValueHolder :: ValueHolder Source #

Create a value of ValueHolder 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:ionText:ValueHolder', valueHolder_ionText - An Amazon Ion plaintext value contained in a ValueHolder structure.

$sel:ionBinary:ValueHolder', valueHolder_ionBinary - An Amazon Ion binary value contained in a ValueHolder structure.-- -- 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.

valueHolder_ionText :: Lens' ValueHolder (Maybe Text) Source #

An Amazon Ion plaintext value contained in a ValueHolder structure.

valueHolder_ionBinary :: Lens' ValueHolder (Maybe ByteString) Source #

An Amazon Ion binary value contained in a ValueHolder structure.-- -- 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.
