use serde::Deserialize;

#[derive(Deserialize, Debug)]
struct Product {
    id: i32,
    title: String,
    description: String,
    price: f64,

async fn getText(url: &str) -> Result<String, Box<dyn std::error::Error>> {
    let body = reqwest::get(url).await?.text().await?;
    Ok(body)
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let body2Result = getText("https://dummyjson.com/products/2").await;

    let product: Product = serde_json::from_str(&body2Result?)?;

    println!("product = {:?}", product);

    tokio::time::sleep(Duration::from_secs(1)).await;

    Ok(())
}

Output
