Type system hints

The jsii compiler interprets some documentation tags as hints that influence the type system represented in the .jsii assembly files.

Forcing an interface to be considered a struct

Using the @struct tag, an interface will be interpreted as a struct even if its name starts with a capital I, followed by another capital letter (which normally would make them be treated as behavioral interfaces):

 * @struct
export interface IPRange {
  readonly cidr: string:


The @struct hint can only be used on interface declarations. Attempting to use them on any other declaration will result in a compilation error.
