bug: Embed Derive and Embedding Documents

[Wilson13]

• I have looked for existing issues (including closed) about this

Bug Report

After following the examples for a while, correct me if I'm wrong, it seems like a lot of the code is either outdated or no longer working.

1. Embed derive macro is not available.
2. Providing more than one Document for EmbeddingsBuilder resulted in panic.

Reproduction

Run this example: https://github.com/0xPlaygrounds/rig/blob/main/rig-core/examples/gemini_embeddings.rs

Expected behavior

Able to run without errors and get embedding results.

Screenshots

1. 
2. 

Additional context

It works only if a single document is provided.

This works.

let embeddings = client
  .embeddings(gemini::embedding::EMBEDDING_004)
  .document(Greetings {
      message: "Hello, world!".to_string(),
  })?
  // .document(Greetings {
  //    message: "Goodbye, world!".to_string(),
  // })?
  .build()
  .await
  .expect("Failed to embed documents");

This doesn't work.

let embeddings = client
  .embeddings(gemini::embedding::EMBEDDING_004)
  .document(Greetings {
      message: "Hello, world!".to_string(),
  })?
  .document(Greetings {
      message: "Goodbye, world!".to_string(),
  })?
  .build()
  .await
  .expect("Failed to embed documents");

Thanks for the amazing work. 🙇

I'm fairly certain you need to have derive trait enabled but I'll ping the author, @marieaurore123

Ok, indeed I just needed to add the derive feature, might have been confused by the different examples. Still looking for a solution for the multiple documents issue.

Marked wontfix because there isn't a specific code change that needs to be made - if you're still having an issue with this please let us know!
