Enum dicom_parser::dataset::DataToken

pub enum DataToken {
    ElementHeader(DataElementHeader),
    SequenceStart {
        tag: Tag,
        len: Length,
    },
    PixelSequenceStart,

}

A token of a DICOM data set stream. This is part of the interpretation of a data set as a stream of symbols, which may either represent data headers or actual value data.

Variants

ElementHeader(DataElementHeader)

A data header of a primitive value.

SequenceStart

The beginning of a sequence element.

Fields of SequenceStart

tag: Taglen: Length

PixelSequenceStart

The beginning of an encapsulated pixel data element.

SequenceEnd

The ending delimiter of a sequence or encapsulated pixel data.

ItemStart

The beginning of a new item in the sequence.

Fields of ItemStart

len: Length

ItemEnd

The ending delimiter of an item.

PrimitiveValue(PrimitiveValue)

A primitive data element value.

ItemValue(Vec<u8>)

An owned piece of raw data representing an item’s value.

This variant is used to represent the value of an offset table or a compressed fragment. It should not be used to represent nested data sets.

Implementations

impl DataToken

pub fn is_sequence_start(&self) -> bool

Check whether this token represents the start of a sequence of nested data sets.

pub fn is_sequence_end(&self) -> bool

Check whether this token represents the end of a sequence or the end of an encapsulated element.

Trait Implementations

impl Clone for DataToken

fn clone(&self) -> DataToken

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataToken

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

Formats the value using the given formatter.

impl Display for DataToken

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

Formats the value using the given formatter.

impl From<DataElementHeader> for DataToken

fn from(header: DataElementHeader) -> Self

Performs the conversion.

impl PartialEq<DataToken> for DataToken

This implementation treats undefined lengths as equal.

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

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

#[must_use]

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

This method tests for !=.
