Enum dicom_core::value::Value

pub enum Value<I> {
    Primitive(PrimitiveValue),
    Sequence {
        items: C<I>,
        size: Length,
    },
}

Representation of a full DICOM value, which may be either primitive or another DICOM object.

Variants

Primitive(PrimitiveValue)

Primitive value

Sequence

A complex sequence of items

Fields of Sequence

items: C<I>

Item collection.

size: Length

The size in bytes.

Methods

impl<I> Value<I> where
    I: DicomValueType, 

pub fn multiplicity(&self) -> u32

Obtain the number of individual values. In a sequence item, this is the number of items.

pub fn primitive(&self) -> Option<&PrimitiveValue>

Gets a reference to the primitive value.

pub fn item(&self) -> Option<&[I]>

Gets a reference to the items.

pub fn into_primitive(self) -> Option<PrimitiveValue>

Retrieves the primitive value.

pub fn into_item(self) -> Option<C<I>>

Retrieves the items.

pub fn to_str(&self) -> Result<Cow<str>, CastValueError>

Retrieves the primitive value as a single string.

If the value contains multiple strings, they are concatenated (separated by '\\') into an owned string.

pub fn as_u8(&self) -> Result<&[u8], CastValueError>

Retrieves the primitive value as a sequence of unsigned bytes.

pub fn as_i32(&self) -> Result<&[i32], CastValueError>

Retrieves the primitive value as a sequence of signed 32-bit integers.

pub fn to_tag(&self) -> Result<Tag, CastValueError>

Retrieves the primitive value as a DICOM tag.

pub fn as_tags(&self) -> Result<&[Tag], CastValueError>

Retrieves the primitive value as a sequence of DICOM tags.

Trait Implementations

impl<I> DicomValueType for Value<I> where
    I: DicomValueType, 

fn value_type(&self) -> ValueType

Retrieve the specific type of this value.

fn size(&self) -> Length

Retrieve the number of values contained.

fn is_empty(&self) -> bool

Check whether the value is empty (0 length).

impl<I> From<PrimitiveValue> for Value<I>

fn from(v: PrimitiveValue) -> Self

Performs the conversion.

impl<I: PartialEq> PartialEq<Value<I>> for Value<I>

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

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

fn ne(&self, other: &Value<I>) -> bool

This method tests for !=.

impl<I: Clone> Clone for Value<I>

fn clone(&self) -> Value<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Debug> Debug for Value<I>

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

Formats the value using the given formatter.
