Enum dicom_core::header::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 of Item

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.

Methods

impl SequenceItemHeader

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

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 Header for SequenceItemHeader

fn tag(&self) -> Tag

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

fn len(&self) -> Length

Retrieve the value data's length as specified by the data element, in bytes. According to the standard, the concrete value size may be undefined, which can be the case for sequence elements or specific primitive values.

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.

impl From<SequenceItemHeader> for DataElementHeader

fn from(value: SequenceItemHeader) -> DataElementHeader

Performs the conversion.

impl PartialEq<SequenceItemHeader> for SequenceItemHeader

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

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 Copy for SequenceItemHeader

impl Debug for SequenceItemHeader

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

Formats the value using the given formatter.
