async functions on docs.rs

[InAnYan]

It seems that async functions on https://docs.rs/langchain-rust/latest/langchain_rust/output_parsers/struct.MarkdownParser.html are in the expanded form (impl Future, etc.).

However, on other crates docs.rs it seems that async can be handled in a less scary way https://docs.rs/ollama-rs/0.1.4/ollama_rs/struct.Ollama.html.

I wonder, why it looks like this. I think showing async fn is better than impl Future<...>

Oh, f**k, it's the async_trait and the problem is with traits... Cause async in traits is experimental
