### jsoncons::cbor::cbor_options
```cpp
#include <jsoncons_ext/cbor/cbor_options.hpp>
class cbor_options;
```
<br>
Specifies options for reading and writing CBOR.
#### Constructors
cbor_options()
Constructs a `cbor_options` with default values.
#### Modifiers
void max_nesting_depth(int depth)
The maximum nesting depth allowed when decoding and encoding CBOR.
Default is 1024. Parsing can have an arbitrarily large depth
limited only by available memory. Serializing a [basic_json](../basic_json.md) to
CBOR is limited by stack size.
cbor_options& pack_strings(bool value)
If set to `true`, then encode will store text strings and
byte strings once, and use string references to represent repeated occurences
of the strings. Decoding the resulting CBOR requires a decoder
that supports the
[stringref extension to CBOR](http://cbor.schmorp.de/stringref), such as
jsoncons itself, or [Perl CBOR::XS](http://software.schmorp.de/pkg/CBOR-XS.html)
If set to `false` (the default), then encode
will encode strings the usual CBOR way.
This option does not affect decode - jsoncons will always decode
string references if present.
cbor_options& use_typed_arrays(bool value)
This option does not affect decode - jsoncons will always decode
typed arrays if present.
