Any Encodings
-------------

### `ANY_PACKED_TYPE_TAG_BYTE_PREFIX`

The encoding consists of a type tag followed by the input value serialized
using a predetermined encoding. This encoding supports the following type tags:

- `0b00000000` (Shared string): If the byte-length is less than 31, the
  byte-length plus 1 is encoded as an unsigned integer in the most-significant
  5 bits of the type tag followed by the current offset minus the offset to the
  start of the UTF-8 string value in the buffer, encoded as a Base-128 64-bit
  Little Endian variable-length unsigned integer. Otherwise, the input value is
  encoded as defined in
  [`FLOOR_PREFIX_LENGTH_ENUM_VARINT`](./string.markdown#floor_prefix_length_enum_varint)
  where `minimum` is 0.
- `0b00000001` (String): If the byte-length is less than 31, the byte-length
  plus 1 is encoded as an unsigned integer in the most-significant 5 bits of
  the type tag followed by the input value as defined in
  [`UTF8_STRING_NO_LENGTH`](./string.markdown#utf8_string_no_length).
  Otherwise, the type tag is followed by the non-shared input value as defined
  in
  [`FLOOR_PREFIX_LENGTH_ENUM_VARINT`](./string.markdown#floor_prefix_length_enum_varint)
  where `minimum` is 0.
- `0b00000010` (Long string): If the byte-length is greater than or equal to 31
  but less than 62, the byte-length minus 31 is encoded as an unsigned integer
  in the most-significant 5 bits of the type tag followed by the input value as
  defined in
  [`UTF8_STRING_NO_LENGTH`](./string.markdown#utf8_string_no_length).
- `0b00000011` (Object): If the number of pairs is greater than 30, the input
  value is encoded as the type tag followed by
  [`ARBITRARY_TYPED_KEYS_OBJECT`](./object.markdown#arbitrary_typed_keys_object)
  where `keyEncoding` is
  [`STRING_UNBOUNDED_SCOPED_PREFIX_LENGTH`](./string.markdown#string_unbounded_scoped_prefix_length)
  and `encoding` is
  [`ANY_PACKED_TYPE_TAG_BYTE_PREFIX`](./any.markdown#any_packed_type_tag_byte_prefix).
  Otherwise, the number of pairs plus 1 is encoded as an unsigned integer in
  the most-significant 5 bits of the type tag followed by the input value
  encoded as defined in
  [`ARBITRARY_TYPED_KEYS_OBJECT_WITHOUT_LENGTH`](./object.markdown#arbitrary_typed_keys_object_without_length)
  where `keyEncoding` is
  [`STRING_UNBOUNDED_SCOPED_PREFIX_LENGTH`](./string.markdown#string_unbounded_scoped_prefix_length)
  and `encoding` is
  [`ANY_PACKED_TYPE_TAG_BYTE_PREFIX`](./any.markdown#any_packed_type_tag_byte_prefix).
- `0b00000100` (Array): If the number of items is greater than 30, the input
  value is encoded as the type tag followed by
  [`FLOOR_TYPED_LENGTH_PREFIX`](./array.markdown#floor_typed_length_prefix)
  where `minimum` is `0`, `prefixEncodings` is `[]`, and `encoding` is
  [`ANY_PACKED_TYPE_TAG_BYTE_PREFIX`](./any.markdown#any_packed_type_tag_byte_prefix).
  Otherwise, the number of items plus 1 is encoded as an unsigned integer in
  the most-significant 5 bits of the type tag followed by the input value
  encoded as defined in
  [`FIXED_TYPED_ARRAY`](./array.markdown#fixed_typed_array) where
  `prefixEncodings` is `[]` and `encoding` is
  [`ANY_PACKED_TYPE_TAG_BYTE_PREFIX`](./any.markdown#any_packed_type_tag_byte_prefix).
- `0b00000101` (Positive integer byte): If the value is less than 31, the value
  plus 1 is encoded as an unsigned integer in the most-significant 5 bits of
  the type tag. Otherwise, the type tag is followed by the input value as
  defined in
  [`BOUNDED_MULTIPLE_8BITS_ENUM_FIXED`](./integer.markdown#bounded_multiple_8bits_enum_fixed)
  where `minimum` is 0 and `maximum` is 255.
- `0b00000110` (Negative integer byte): If the absolute value minus 1 is less
  than 31, the absolute value plus 1 is encoded as an unsigned integer in the
  most-significant 5 bits of the type tag. Otherwise, the type tag is followed
  by the absolute input value minus 1 as defined in
  [`BOUNDED_MULTIPLE_8BITS_ENUM_FIXED`](./integer.markdown#bounded_multiple_8bits_enum_fixed)
  where `minimum` is 0 and `maximum` is 255.
- `0b00000111` (False): The `false` constant.
- `0b00001111` (True): The `true` constant.
- `0b00010111` (Null): The `null` constant.
- `0b00011111` (Positive integer): The type tag is followed by the input value
  as defined in
  [`FLOOR_MULTIPLE_ENUM_VARINT`](./integer.markdown#floor_multiple_enum_varint).
- `0b00100111` (Negative integer): The type tag is followed by the absolute
  input value minus 1 as defined in
  [`FLOOR_MULTIPLE_ENUM_VARINT`](./integer.markdown#floor_multiple_enum_varint).
- `0b00101111` (Number): The type tag is followed by the input value as defined
  in [`DOUBLE_VARINT_TUPLE`](./number.markdown#double_varint_tuple).
- `0b00111111` (Long string with base exponent 7): The type tag is followed by
  the byte-length of the string as defined in
  [`FLOOR_MULTIPLE_ENUM_VARINT`](./integer.markdown#floor_multiple_enum_varint)
  where `minimum` is `2 ** 7` followed by the input value encoded as defined in
  [`UTF8_STRING_NO_LENGTH`](./string.markdown#utf8_string_no_length).
- `0b01000111` (Long string with base exponent 8): The type tag is followed by
  the byte-length of the string as defined in
  [`FLOOR_MULTIPLE_ENUM_VARINT`](./integer.markdown#floor_multiple_enum_varint)
  where `minimum` is `2 ** 8` followed by the input value encoded as defined in
  [`UTF8_STRING_NO_LENGTH`](./string.markdown#utf8_string_no_length).
- `0b01001111` (Long string with base exponent 9): The type tag is followed by
  the byte-length of the string as defined in
  [`FLOOR_MULTIPLE_ENUM_VARINT`](./integer.markdown#floor_multiple_enum_varint)
  where `minimum` is `2 ** 9` followed by the input value encoded as defined in
  [`UTF8_STRING_NO_LENGTH`](./string.markdown#utf8_string_no_length).
- `0b01010111` (Long string with base exponent 10): The type tag is followed by
  the byte-length of the string as defined in
  [`FLOOR_MULTIPLE_ENUM_VARINT`](./integer.markdown#floor_multiple_enum_varint)
  where `minimum` is `2 ** 10` followed by the input value encoded as defined
  in [`UTF8_STRING_NO_LENGTH`](./string.markdown#utf8_string_no_length).

#### Options

None

#### Conditions

None

#### Examples

Given the input value `[ "foo", true, 2000 ]`, the encoding results in:

```
+------+------+------+------+------+------+------+------+------+
| 0x24 | 0x21 | 0x66 | 0x6f | 0x6f | 0x0f | 0x1f | 0xd0 | 0x0f |
+------+------+------+------+------+------+------+------+------+
                f      o      o      true          ^^^^^^^^^^^
								                                   2000
