This tutorial probably needs updating. I was not able to find rig::rag::RagAgent and then I see in the [CHANGELOG](https://github.com/0xPlaygrounds/rig/blob/6f12c974b2eac7d7bb1f7ac94445bd6e726d737b/rig-core/CHANGELOG.md?plain=1#L226) that it has been deprecated: - Deprecate RagAgent and Model in favor of versatile Agent I am not sure how to make the adjustment from RagAgent to versatile Agent. There are also a few other items I had to change. I had to add these two imports: use rig::vector_store::in_memory_store::InMemoryVectorIndex; use rig::vector_store::VectorStore; And I was not able to get the \`\`\` to compile so I have to wrap the string with r#...#. I was not able to complete the tutorial because of the RagAgent issue, so I look forward to an update soon.
