structures, see [RFC 9052 2. Basic COSE Structure](https://www.rfc-editor.org/rfc/rfc9052#section-2). - ### Custom CBOR-specific Serializers Cbor encoders and decoders implement the interfaces [CborEncoder](CborEncoder.kt) and [CborDecoder](CborDecoder.kt), respectively. These interfaces contain a single property, `cbor`, exposing the current CBOR serialization configuration. This enables custom cbor-specific serializers to reuse the current `Cbor` instance to produce embedded byte arrays or react to configuration settings such as `preferCborLabelsOverNames` or `useDefiniteLengthEncoding`, for example. + +### CBOR Elements + +Aside from direct conversions between bytearray and CBOR objects, Kotlin serialization offers APIs that allow +other ways of working with CBOR in the code. For example, you might need to tweak the data before it can parse +or otherwise work with such unstructured data that it does not readily fit into the typesafe world of Kotlin +serialization. + +The main concept in this part of the library is [CborElement]. Read on to learn what you can do with it. + +#### Encoding from/to `CborElement` + +Bytes can be decoded into an instance of `CborElement` with the [Cbor.decodeFromByteArray] function by either manually +specifying [CborElement.serializer()] or specifying [CborElement] as generic type parameter. +It is also possible to encode arbitrary serializable structures to a `CborElement` through [Cbor.encodeToCborElement]. + +Since these operations use the same code paths as regular serialization (but with specialized serializers), the config flags +behave as expected: + +```kotlin +fun main() { + val element: CborElement = Cbor.decodeFromHexString("a165627974657343666f6f") + println(element) +} +``` + +The above snippet will print the following diagnostic notation + +```text +CborMap(tags=[], content={CborString(tags=[], value=bytes)=CborByteString(tags=[], value=h'666f6f)}) +``` + +#### Tagging `CborElement`s + +Every CborElement—whether it is used as a property, a value inside a collection, or even a complex key inside a map +(which is perfectly legal in CBOR)—supports tags. Tags can be specified by passing them s varargs parameters upon +CborElement creation. +For example, take following structure (represented in diagnostic notation): + + + +```hexdump +bf # map(*) + 61 # text(1) + 61 # "a" + cc # tag(12) + 1a 0fffffff # unsigned(268,435,455) + d8 22 # base64 encoded text, tag(34) + 61 # text(1) + 62 # "b" + # invalid length at 0 for base64 + 20 # negative(-1) + d8 38 # tag(56) + 61 # text(1) + 63 # "c" + d8 4e # typed array of i32, little endian, twos-complement, tag(78) + 42 # bytes(2) + cafe # "\xca\xfe" + # invalid data length for typed array + 61 # text(1) + 64 # "d" + d8 5a # tag(90) + cc # tag(12) + 6b # text(11) + 48656c6c6f20576f726c64 # "Hello World" + ff # break +``` + +Decoding it results in the following CborElement (shown in manually formatted diagnostic notation): + +``` +CborMap(tags=[], content={ + CborString(tags=[], value=a) = CborPositiveInt( tags=[12], value=268435455), + CborString(tags=[34], value=b) = CborNegativeInt( tags=[], value=-1), + CborString(tags=[56], value=c) = CborByteString( tags=[78], value=h'cafe), + CborString(tags=[], value=d) = CborString( tags=[90, 12], value=Hello World) +}) +``` + +##### Caution + +Tags are properties of `CborElements`, and it is possible to mixing arbitrary serializable values with `CborElement`s that +contain tags inside a serializable structure. It is also possible to annotate any [CborElement] property +of a generic serializable class with `@ValueTags`. +**This can lead to asymmetric behavior when serializing and deserializing such structures!** + +#### Types of CBOR Elements + +A [CborElement] class has three direct subtypes, closely following CBOR grammar: + +* [CborPrimitive] represents primitive CBOR elements, such as string, integer, float boolean, and null. + CBOR byte strings are also treated as primitives + Each primitive has a [value][CborPrimitive.value].

It is a Kotlin [List] of `CborElement` items. + +* [CborMap] represents a CBOR map/object.
