Struct ElementMeta 

pub struct ElementMeta {
    pub path: &'static str,
    pub min: u32,
    pub max: &'static str,
    pub is_summary: bool,
    pub binding: Option<BindingMeta>,
    pub types: &'static [TypeRef],
    pub content_reference: Option<&'static str>,
}

Metadata for one element of a FHIR resource or datatype, keyed by its full ElementDefinition path.

Fields

path: &'static str

Full FHIR path, e.g. "Patient.gender" or "Observation.value[x]".

min: u32

Minimum cardinality.

max: &'static str

Maximum cardinality as the raw FHIR token: "0", "1", "*", or a number.

is_summary: bool

Whether the element is part of the summary view (ElementDefinition.isSummary).

binding: Option<BindingMeta>

Coded-value binding, if any.

types: &'static [TypeRef]

Allowed types; more than one for a value[x] choice element.

content_reference: Option<&'static str>

The element path whose content defines this one, for the recursive backbones FHIR expresses with contentReference.

Questionnaire.item.item does not restate an item’s elements; it points at Questionnaire.item. The target is not always an ancestor — TestScript.test.action.operation refers to TestScript.setup.action.operation — so it cannot be recovered from the path and has to be carried here.

Implementations

impl ElementMeta

pub fn is_required(&self) -> bool

Whether the element is mandatory (minimum cardinality ≥ 1).

pub fn is_multiple(&self) -> bool

Whether the element repeats (maximum cardinality greater than one).

pub fn is_choice(&self) -> bool

Whether the element is a value[x]-style choice element.

pub fn type_codes(&self) -> impl Iterator<Item = &'static str>

The FHIR type codes allowed for this element.

Trait Implementations

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

Performs copy-assignment from source.

impl Copy for ElementMeta

impl Debug for ElementMeta

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

Formats the value using the given formatter.
