Unable to use @DependencyEndpoint with a typealias

[JOyo246]

Description

Not sure if this is a dependencies bug, macros bug, or macros feature?

works!

extension MyFeature {
  @DependencyClient
  struct Client {
    var refreshRequest: @Sendable (MyFeaturesRequest) async throws -> MyFeaturesRequest.Content
  }
}

---

Doesnt work

extension MyFeature {
  @DependencyClient
  struct Client {
    var refreshRequest: RequestOf<MyFeaturesRequest>
  }
}

typealias RequestOf<R: NetworkRequestProtocol> = @Sendable (R) async throws -> R.Content

Checklist

• I have determined whether this bug is also reproducible in a vanilla SwiftUI project.
• If possible, I've reproduced the issue using the main branch of this package.
• This issue hasn't been addressed in an existing GitHub issue or discussion.

Expected behavior

I'd expect the DependencyEndpoint macro to work, when the typealias is representing a closure.

Actual behavior

The DependencyEndpoint macro doesn't apply when the typealias is representing a closure.

Hi @JOyo246, this is a limitation of macros. The @DependencyClient macro can only see the syntax it is directly attached to, so it has no idea what RequestOf is. So unfortunately you cannot use type aliases in this way.

Since this isn't an issue with the library I am going to convert it to a discussion.
