I've seen a lot of examples of how to get a list of User Defined
Attributes from a known symbol but I haven't seen any for how to
get a list of symbols when only the UDA is known.
The use case is the same as seen in Rust with Serde[1]. Library
users annotate a struct to mark it for serialization. In Java and
Spring, you can mark a method with @Secured to add authorization
to an endpoint[2]. In both of these cases, you have no idea which
symbol the UDA will be applied to.
So far I've only seen a way to get unknown UDAs from known
symbols but not how to get unknown symbols from UDAs. Is there
any documentation for how to get a list of symbols annotated with
a specific UDA?
