Struct Extension 

pub struct Extension {
    pub id: Option<String>,
    pub extension: Option<Vec<Box<Extension>>>,
    pub url: String,
    pub value: Option<ExtensionValueTypeChoice>,
}

Optional Extension Element - found in all resources.

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.

url: String

Source of the definition for the extension code - a logical name or a URL.

value: Option<ExtensionValueTypeChoice>

Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).
