Struct PrimVec 

pub struct PrimVec<T>(pub Vec<Option<T>>);

The values of a repeating FHIR primitive element (0..*).

A thin, transparent wrapper over Vec<Option<T>>: None is an extension-only placeholder — the JSON null whose position in the paired _element array carries the extension. Use values to iterate the actual values, iter to see positions.

A placeholder with no corresponding _element entry is meaningless in FHIR; nothing here prevents constructing one, but the serializer will faithfully write the null, and validation flags it (Validate for PrimVec).

Tuple Fields

0: Vec<Option<T>>

Implementations

impl<T> PrimVec<T>

pub fn new() -> Self

An empty value array.

pub fn len(&self) -> usize

Number of positions, placeholders included.

pub fn is_empty(&self) -> bool

True when there are no positions at all.

pub fn values(&self) -> impl Iterator<Item = &T>

The values, skipping extension-only placeholders.

pub fn iter(&self) -> Iter<'_, Option<T>>

Every position: Some(value) or None for a placeholder.

pub fn push(&mut self, value: T)

Append a value.

pub fn push_placeholder(&mut self)

Append an extension-only placeholder (a JSON null; its extension lives at the same index of the _element sibling field).

pub fn first_value(&self) -> Option<&T>

The first actual value, if any position holds one.

Trait Implementations
