```suggestion
    ) -> BoxStream<'a, JoinHandle<(Result<Vec<String>, serde_json::Value)>>> {
```

in future, `serde_json::Value` might contains a value coming from a fail-able source.

Code after:

pub struct StructuredDocBuilder {
    embedding: Arc<dyn Embedding>,
}

impl StructuredDocBuilder {
    pub fn new(embedding: Arc<dyn Embedding>) -> Self {
        Self { embedding }
    }
}

#[async_trait]
impl IndexAttributeBuilder<StructuredDoc> for StructuredDocBuilder {
    async fn build_attributes(&self, document: &StructuredDoc) -> serde_json::Value {
        let mut attributes = document.build_attributes().await;
        attributes
            .as_object_mut()
            .unwrap()
            .insert(structured_doc::fields::KIND.into(), json!(document.kind()));
        attributes
    }

    async fn build_chunk_attributes<'a>(
        &self,

Review comment (suggestion):
I prefer use icon `settings` than `gear` as VSCode settings page use this icon.
