DNSClient doesn’t conform to the Sendable protocol

[vamsii777]

I’ve got a bit of a bug with MongoKitten’s Cluster.swift. It’s throwing a bunch of compiler errors about the Sendable protocol. Specifically, the DNSClient and ResourceRecord types aren’t following the rules.

Here’s how you can reproduce the issue:

1. Add MongoKitten (v7.9.5) to your project.
2. Run the code.
3. Watch the compiler errors in Cluster.swift.

The code should compile without these errors. The DNSClient and ResourceRecord types should be Sendable.

I’ve also found the errors in Cluster.swift:

• Line 321: Type ‘DNSClient’ doesn’t conform to the ‘Sendable’ protocol
• Line 323: Type ‘DNSClient’ doesn’t conform to the ‘Sendable’ protocol
• Line 335: Type ‘ResourceRecord<SRVRecord>’ doesn’t conform to the ‘Sendable’ protocol

This bug seems to be linked to Swift concurrency stuff. I think it might need an update to the DNSClient dependency.
