# Helpers for Fastly's Compute@Edge Synthetic Content Tutorial

This crate exports a (de)serializable [`struct ForecastAPIResponse`](./src/lib.rs) for [WeatherAPI](https://weatherapi.com)'s [Forecast](https://www.weatherapi.com/api-explorer.aspx#forecast) endpoint response. 

The ensuing data structure supports the creation of a Weather Widget during the [Synthetic Content Tutorial](https://developer.fastly.com/solutions/tutorials/synthetic/) using Fastly's [Compute@Edge](https://developer.fastly.com/learning/compute/rust/).

## Use with [`Response.take_body_json<T: DeserializeOwned>`](https://docs.rs/fastly/latest/fastly/http/struct.Response.html#method.take_body_json)
```rust
let url = format!(
    "http://api.weatherapi.com/v1/forecast.json?q={},{}&key={}",
    LATITUDE,
    LONGITUDE,
    MY_API_KEY
);

let mut resp = Request::new(Method::GET, url)
    .with_pass(true)
    .send(BACKEND_NAME)?;

// Parse the JSON response body into an ForecastAPIResponse
let api_response = resp.take_body_json::<ForecastAPIResponse>()?;
```
