Symbols are values from a constrained domain. Although the set of possible domains is open-ended, typically the both number and size of symbols in use for any given application will be small, e.g. small enough that it is reasonable to cache all the distinct values. Symbols are encoded as ASCII characters ASCII.

List(Vec<Value>)

Map(OrderedMap<Value, Value>)

A polymorphic mapping from distinct keys to values.

encoding name = “map8”, encoding code = 0xc1, category = compound, width = 1 label=“up to 2^8 - 1 octets of encoded map data”

encoding name = “map32”, encoding code = 0xd1, category = compound, width = 4 label=“up to 2^32 - 1 octets of encoded map data

Map encodings MUST contain an even number of items (i.e. an equal number of keys and values). A map in which there exist two identical key values is invalid. Unless known to be otherwise, maps MUST be considered to be ordered, that is, the order of the key-value pairs is semantically important and two maps which are different only in the order in which their key-value pairs are encoded are not equal.

Note: Can only use BTreeMap as it must be considered to be ordered

Array(Array<Value>)

A sequence of values of a single type.

encoding name = “array8”, encoding code = 0xe0 category = array, width = 1, label=“up to 2^8 - 1 array elements with total size less than 2^8 octets”

encoding name = “array32”, encoding code = 0xf0, category = array, width = 4 label=“up to 2^32 - 1 array elements with total size less than 2^32 octets”
