Struct dicom_core::header::DataElementRef

pub struct DataElementRef<'v, I: 'v, P: 'v> { /* private fields */ }

A data type that represents a DICOM data element with a borrowed value.

Implementations

impl<'v, I, P> DataElementRef<'v, I, P>where
    I: HasLength,

pub fn new(tag: Tag, vr: VR, value: &'v Value<I, P>) -> Self

Create a data element from the given parts. This method will not check whether the value representation is compatible with the value. Caution is advised.

pub fn vr(&self) -> VR

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

pub fn value(&self) -> &Value<I, P>

Retrieves the DICOM value.

Trait Implementations

impl<'v, I: Clone + 'v, P: Clone + 'v> Clone for DataElementRef<'v, I, P>

fn clone(&self) -> DataElementRef<'v, I, P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'v, I: Debug + 'v, P: Debug + 'v> Debug for DataElementRef<'v, I, P>

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

Formats the value using the given formatter.

impl<'v, I, P> HasLength for DataElementRef<'v, I, P>

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<'v, I, P> Header for DataElementRef<'v, I, P>

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<'v, I: PartialEq + 'v, P: PartialEq + 'v> PartialEq<DataElementRef<'v, I, P>> for DataElementRef<'v, I, P>

fn eq(&self, other: &DataElementRef<'v, I, P>) -> bool

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

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.
