How do i get/parse Results from search, I get errors when I try...

[saent-x]

My Implementation

pub async fn search_playlist(&self, search_items: Vec<LLMResult>) -> Result<Option<Song>, Box<dyn std::error::Error>>{
        self.client.request_token().await?;
        
        let mut results: Vec<Song> = vec![];
        
        for llmresult in search_items {
            let query = format!("track:{} artist:{} year:{}", 
                llmresult.title.unwrap_or_default(), 
                llmresult.artist.unwrap_or_default(), 
                llmresult.year.unwrap_or_default()
            );
                
            let result = self.client.search(&query, SearchType::Track, None, None, Some(1), None).await?;
            
            let song = match result {
                Ok(tracks) => tracks,
                Err(err) => return Err(err)
            };
            results.push(song);
        }
        
        Ok(None)
    }

What am I doing wrong? I get error "rustc: mismatched types
expected enum rspotify::rspotify_model::SearchResult
found enum Result<_, _>"

The error occurs because self.client.search() returns a Result<SearchResult, rspotify::Error>, but you are trying to match result as if it were already an Ok(tracks) instead of properly handling the Result.

        // `search` returns a Result<SearchResult, rspotify::Error>
        let search_result = self.client.search(&query, SearchType::Track, None, None, Some(1), None).await?; // `?` mean unwrap the Result to Ok(tracks)

you could just remove ?

Hi @ramsayleung ,

I implemented the match based on your response and stored in a variabke, but I still can't access the tracks from the result...

let search_result = match result {
                Ok(a) => a,
                Err(err) => return Err(err)
};
