//! Represent Google Trend Related Topics list. //! //! Users searching for your keywords also searched for these topics. //! You can view by the following metrics: //! - Top - The most popular topics. //! Scoring is on a relative scale where a value of 100 is the most commonly searched topic and a value of 50 is a topic searched half as often as the most popular term, and so on. //! - Rising //! Related topics with the biggest increase in search frequency since the last time period. //! Results marked "Breakout" had a tremendous increase, probably because these topics are new and had few (if any) prior searches. use crate::client::*; use crate::request_handler::Query; use serde_json::Value; #[derive(Clone, Debug, Default)] pub struct RelatedTopics { pub client: Client, } impl RelatedTopics { pub fn new(client: Client) -> RelatedTopics { RelatedTopics { client } } /// Retrieve Topics data for all keywords. /// /// Retrieve data for all keywords set within the client. /// /// Returns a JSON serde Value (serde_json::Value). /// /// # Example /// ``` /// # use rtrend::{Country, Keywords, Client, RelatedTopics}; /// let keywords = Keywords::new(vec!["Github vs Gitlab"]); /// let country = Country::new("ALL"); /// let client = Client::new(keywords, country).build(); /// /// let related_topics = RelatedTopics::new(client).get(); /// /// println!("{}", related_topics); /// ``` /// /// # Panics /// Panic if the client have not been built. /// /// ```should_panic /// # use rtrend::{Country, Keywords, Client, RelatedTopics}; /// let keywords = Keywords::new(vec!["hacker"]); /// let country = Country::new("US"); /// /// // Client not built /// let client = Client::new(keywords, country); /// /// let related_topics = RelatedTopics::new(client).get(); /// ``` pub fn get(&self) -> Value { let value = self .send_request() .into_iter() .map(|x| x.to_string()) .collect::<Vec<String>>(); let joined = value.join(","); let form: String = format!("[{}]", joined); serde_json::from_str(form.as_str()).unwrap() } /// Retrieve Topics data for a specific keywords. /// /// Retrieve data for a specific keyword set within the client. /// /// Returns a JSON serde Value (serde_json::Value). /// /// ```rust /// # use rtrend::{Country, Keywords, Client, RelatedTopics}; /// let keywords = Keywords::new(vec!["Github", "Gitlab"]); /// let country = Country::new("ALL"); /// let client = Client::new(keywords, country).build(); /// /// let related_topics = RelatedTopics::new(client).get_for("Gitlab"); /// /// println!("{}", related_topics); /// ``` pub fn get_for(&self, keyword: &str) -> Value { let index = self .client .keywords .keywords .iter() .position(|&x| x == keyword); let keyword_index = match index { Some(k) => k, None => panic!("The keyword {} is not set with the client", keyword), }; self.send_request()[keyword_index].clone() } }
