Specialised collection types

Smithy supports list and set, Smithy4s renders that to List[A] and Set[A] respectively. You can also use the @uniqueItems annotation on list which is equivalent to set.

Smithy4s has support for two specialized collection types: Vector and IndexedSeq. The following examples show how to use them:

use smithy4s.meta#indexedSeq
use smithy4s.meta#vector

@indexedSeq
list SomeIndexSeq {
  member: String
}

@vector
list SomeVector {
  member: String
}

Both annotations are only applicable on list shapes. You can't mix @vector with @indexedSeq, and neither one can be used with @uniqueItems.
