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

Fields

tag: Tag

len: Length

The beginning of a sequence element.

PixelSequenceStart

The beginning of an encapsulated pixel data element.

SequenceEnd

The ending delimiter of a sequence or encapsulated pixel data.

ItemStart

Fields

len: Length

The beginning of a new item in the sequence.

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 encoded fragment. It should not be used to represent nested data sets.

OffsetTable(Vec<u32>)

An owned sequence of unsigned 32 bit integers representing a pixel data offset table.

This variant is used to represent the byte offsets to the first byte of the Item tag of the first fragment for each frame in the sequence of items, as per PS 3.5, Section A.4.

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.

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

Converts to this type from the input type.

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 ==.

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.
