Sub-fields of the constraint field in ElementDefinition

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.

key: String

Target of ‘condition’ reference above

Allows identification of which elements have their cardinalities impacted by the constraint. Will not be referenced for constraints that do not affect cardinality.

key_ext: Option<FieldExtension>

Extension field.

requirements: Option<String>

Why this constraint is necessary or appropriate

Description of why this constraint is necessary or appropriate.

To be used if the reason for the constraint might not be intuitive to all implementers.

requirements_ext: Option<FieldExtension>

Extension field.

severity: ConstraintSeverity

ConstraintSeverity; error | warning

Identifies the impact constraint violation has on the conformance of the instance.

This allows constraints to be asserted as “shall” (error) and “should” (warning).

severity_ext: Option<FieldExtension>

Extension field.

suppress: Option<bool>

Suppress warning or hint in profile

If true, indicates that the warning or best practice guideline should be suppressed.

This element should only be present in a derived profile where a warning or hint has been determined to be spurious/incorrect. E.g. a warning encouraging the inclusion of an element that the profile explicitly prohibits.

suppress_ext: Option<FieldExtension>

Extension field.

human: String

Human description of constraint

Text that can be used to describe the constraint in messages identifying that the constraint has been violated.

Should be expressed in business terms as much as possible.

human_ext: Option<FieldExtension>

Extension field.

expression: Option<String>

FHIRPath expression of constraint

A FHIRPath expression of constraint that can be executed to see if this constraint is met.

In the absense of an expression, the expression is likely not enforceable by validators, and might be missed by many systems.

expression_ext: Option<FieldExtension>

Extension field.

source: Option<String>

Reference to original source of constraint

A reference to the original source of the constraint, for traceability purposes.

This is used when, e.g. rendering, where it is not useful to present inherited constraints when rendering the snapshot.

source_ext: Option<FieldExtension>

Extension field.

Implementations

impl ElementDefinitionConstraint

pub fn builder() -> ElementDefinitionConstraintBuilder

Start building a new instance

Trait Implementations

impl Clone for ElementDefinitionConstraint

fn clone(&self) -> ElementDefinitionConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ElementDefinitionConstraint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ElementDefinitionConstraint

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ElementDefinitionConstraint

fn eq(&self, other: &ElementDefinitionConstraint) -> 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 ElementDefinitionConstraint

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.
