+The library also supports binary types from BSON, CBOR (byte strings), and MessagePack (bin, ext, fixext). They are stored by default as `std::vector<std::uint8_t>` to be processed outside of the library.

+```cpp
+// CBOR byte string with payload 0xCAFE
+std::vector<std::uint8_t> v = {0x42, 0xCA, 0xFE};
+
+// read value
+json j = json::from_cbor(v);
+
+// the JSON value has type binary
+j.is_binary(); // true
+
+// get reference to stored binary value
+auto& binary = j.get_binary();
+
+// the binary value has no subtype (CBOR has no binary subtypes)
+binary.has_subtype(); // false
+
+// access std::vector<std::uint8_t> member functions
+binary.size(); // 2
+binary[0]; // 0xCA
+binary[1]; // 0xFE
