Enum dicom_core::ops::AttributeSelectorStep

pub enum AttributeSelectorStep {
    Tag(Tag),
    Nested {
        tag: Tag,
        item: u32,
    },
}

A single step of an attribute selection.

A selector step may either select an element directly at the root (Tag) or a specific item in a sequence to navigate into (Nested).

A full attribute selector can be specified by using a sequence of these steps (but should always end with the Tag variant, otherwise the operation would be unspecified).

Variants

Tag(Tag)

Select the element with the tag reachable at the root of this data set

Nested

Fields

tag: Tag

item: u32

Select an item in a data set sequence, as an intermediate step

Trait Implementations

impl Clone for AttributeSelectorStep

fn clone(&self) -> AttributeSelectorStep

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeSelectorStep

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

Formats the value using the given formatter.

impl Display for AttributeSelectorStep

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

Displays the attribute selector step: (GGGG,EEEE) if Tag,, (GGGG,EEEE)[i] if Nested

impl From<(Tag, u32)> for AttributeSelectorStep

fn from((tag, item): (Tag, u32)) -> Self

Creates a sequence item selector step by data element tag and item index.

impl From<Tag> for AttributeSelectorStep

fn from(value: Tag) -> Self

Creates an attribute selector step by data element tag.

impl Hash for AttributeSelectorStep

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<AttributeSelectorStep> for AttributeSelectorStep

fn eq(&self, other: &AttributeSelectorStep) -> 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.
