Enum SequenceItemHeader

pub enum SequenceItemHeader {
    Item {
        len: Length,
    },
    ItemDelimiter,
    SequenceDelimiter,
}

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

Variants

Item

The cursor contains an item.

Fields

len: Length

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

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

impl SequenceItemHeader

pub fn new<T: Into<Tag>>( tag: T, len: Length, ) -> Result<SequenceItemHeader, SequenceItemHeaderError>

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.

Trait Implementations

impl Clone for SequenceItemHeader

fn clone(&self) -> SequenceItemHeader

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SequenceItemHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<SequenceItemHeader> for DataElementHeader

fn from(value: SequenceItemHeader) -> DataElementHeader

Converts to this type from the input type.

impl HasLength for SequenceItemHeader

fn length(&self) -> Length

Retrieve the value data’s length as specified by the data element or item, in bytes.

fn is_empty(&self) -> bool

Check whether the value is empty (0 length).

impl Header for SequenceItemHeader

fn tag(&self) -> Tag

Retrieve the element’s tag as a (group, element) tuple.

fn is_item(&self) -> bool

Check whether this is the header of an item.

fn is_item_delimiter(&self) -> bool

Check whether this is the header of an item delimiter.

fn is_sequence_delimiter(&self) -> bool

Check whether this is the header of a sequence delimiter.

fn is_encapsulated_pixeldata(&self) -> bool

Check whether this is the header of an encapsulated pixel data.

impl PartialEq for SequenceItemHeader

fn eq(&self, other: &SequenceItemHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
