Expand description

Data type for describing a sequence item data element. If the element represents an item, it will also contain the specified length.

Variants

Item

Fields

len: Length

the length of the item in bytes (can be 0xFFFFFFFF if undefined)

The cursor contains an item.

ItemDelimiter

The cursor read an item delimiter. The element ends here and should not be read any further.

SequenceDelimiter

The cursor read a sequence delimiter. The element ends here and should not be read any further.

Implementations

Create a sequence item header using the element’s raw properties. An error can be raised if the given properties do not relate to a sequence item, a sequence item delimiter or a sequence delimiter.
