Struct ElementDefinitionConstraint 

pub struct ElementDefinitionConstraint {
    pub id: Option<String>,
    pub extension: Option<Vec<Box<Extension>>>,

}

Formal constraints such as co-occurrence and other constraints that can be computationally evaluated within the context of the instance.

Fields

id: Option<String>

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

extension: Option<Vec<Box<Extension>>>

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 manageable, 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.

key: Box<FHIRId>

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

requirements: Option<Box<FHIRString>>

Description of why this constraint is necessary or appropriate.

severity: Box<ConstraintSeverity>

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

human: Box<FHIRString>

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

expression: Option<Box<FHIRString>>

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

xpath: Option<Box<FHIRString>>

An XPath expression of constraint that can be executed to see if this constraint is met.

source: Option<Box<FHIRCanonical>>

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