}

The value held by a DICOM data element.

Each variant corresponds to one or more DICOM VRs. Numeric string VRs (DS, IS) are stored already decoded as f64/i64.

Variants

Empty

No value (zero-length element).

Strings(Vec<String>)

AE, CS, LO, LT, SH, ST, UC, UR, UT — multi-valued via backslash.

PersonNames(Vec<PersonName>)

PN — person name with up to three component groups.

Uid(String)

UI — UID string.

Date(Vec<DicomDate>)

DA — date values.

Time(Vec<DicomTime>)

TM — time values.

DateTime(Vec<DicomDateTime>)

DT — datetime values.

Ints(Vec<i64>)

IS — integer string, decoded.

Decimals(Vec<f64>)

DS — decimal string, decoded.

U8(Vec<u8>)

OB, UN — raw bytes.

U16(Vec<u16>)

US, OW — raw 16-bit words (interpret by VR).

I16(Vec<i16>)

SS — signed 16-bit integers.

U32(Vec<u32>)

UL, OL — 32-bit unsigned integers.

I32(Vec<i32>)

SL — 32-bit signed integers.

U64(Vec<u64>)

UV, OV — 64-bit unsigned integers.

I64(Vec<i64>)

SV — 64-bit signed integers.

F32(Vec<f32>)

FL, OF — 32-bit floats.

F64(Vec<f64>)

FD, OD — 64-bit floats.

Tags(Vec<Tag>)

AT — attribute tag pairs.

Sequence(Vec<DataSet>)

SQ — sequence of items (datasets).

PixelData(PixelData)

Pixel data — (7FE0,0010).

Implementations

impl Value

pub fn multiplicity(&self) -> usize

Returns the number of values (VM).

pub fn is_empty(&self) -> bool

pub fn as_string(&self) -> Option<&str>

Returns the first string value, if this is a Strings or Uid variant.

pub fn as_strings(&self) -> Option<&[String]>

pub fn as_u16(&self) -> Option<u16>

pub fn as_u32(&self) -> Option<u32>

pub fn as_i32(&self) -> Option<i32>

pub fn as_f64(&self) -> Option<f64>

pub fn as_bytes(&self) -> Option<&[u8]>

pub fn to_display_string(&self) -> String

Returns a human-readable string representation (like dcmdump output).

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl PartialEq for Value

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

Tests for self and other values to be equal, and is used by ==.

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

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