Struct dicom_core::header::DataElementHeader

pub struct DataElementHeader {
    pub tag: Tag,
    pub vr: VR,
    pub len: Length,
}

A data structure for a data element header, containing a tag, value representation and specified length.

Fields

tag: Tag

DICOM tag

vr: VR

Value Representation

len: Length

Element length

Implementations

impl DataElementHeader

pub fn new<T: Into<Tag>>(tag: T, vr: VR, len: Length) -> DataElementHeader

Create a new data element header with the given properties. This is just a trivial constructor.

pub fn vr(&self) -> VR

Retrieve the element’s value representation, which can be unknown.

pub fn is_non_primitive(&self) -> bool

Check whether the header suggests the value to be a sequence value: if the value representation is SQ or the length is undefined.

Trait Implementations

impl Clone for DataElementHeader

fn clone(&self) -> DataElementHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataElementHeader

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 DataElementHeader

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 DataElementHeader

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<DataElementHeader> for DataElementHeader

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

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

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

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