Expression Type: A expression that is evaluated in a specified context and returns a value. The context of use of the expression must specify the context in which the expression is evaluated, and how the result of the expression is used.

Expression v5.0.0

An expression that can be used to generate a value

A expression that is evaluated in a specified context and returns a value. The context of use of the expression must specify the context in which the expression is evaluated, and how the result of the expression is used.

Fields

id: Option<String>

Unique id for inter-element referencing

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

extension: Vec<Extension>

Additional content defined by implementations

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

description: Option<String>

Natural language description of the condition

A brief, natural language description of the condition that effectively communicates the intended semantics.

description_ext: Option<FieldExtension>

Extension field.

name: Option<String>

Short name assigned to expression for reuse

A short name assigned to the expression to allow for multiple reuse of the expression in the context where it is defined.

name_ext: Option<FieldExtension>

Extension field.

language: Option<String>

ExpressionLanguage; text/cql | text/fhirpath | application/x-fhir-query | etc.

The media type of the language for the expression.

language_ext: Option<FieldExtension>

Extension field.

expression: Option<String>

Expression in specified language

An expression in the specified language that returns a value.

If Expression.expression and Expression.reference are both present, the Expression.expression might just be a name pointing something within the referenced content.

expression_ext: Option<FieldExtension>

Extension field.

reference: Option<String>

Where the expression is found

A URI that defines where the expression is found.

If both a reference and an expression is found, the reference SHALL point to the same expression.

reference_ext: Option<FieldExtension>

Extension field.

Trait Implementations

impl Clone for ExpressionInner

fn clone(&self) -> ExpressionInner

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpressionInner

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExpressionInner

fn deserialize<__D>( __deserializer: __D, ) -> Result<ExpressionInner, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ExpressionInner> for Expression

fn from(inner: ExpressionInner) -> Expression

Converts to this type from the input type.

impl PartialEq for ExpressionInner

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

impl Serialize for ExpressionInner

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
