//! Parses the JSON returned by the [ADS-B Exchange
//! API](https://www.adsbexchange.com/data/).
//!
//! This crate currently only supports v2 of the API.
//!
//! To parse a v2 JSON response:
//!
//! ```
//! use adsbx_json::v2::Response;
//! use std::str::FromStr;
//!
//! # let json_str = include_str!("../tests/v2-specimen-nearby.json");
//! let response = Response::from_str(&json_str).unwrap();
//! println!("Got {} aircraft", response.aircraft.len());
//! let ac = &response.aircraft[0];
//! println!("ICAO: {}", ac.hex);
//! if let Some(reg) = &ac.registration {
//!     println!("Registration: {}", reg);
//! }
//! if let (Some(lat), Some(lon)) = (ac.lat, ac.lon) {
//!     println!("Aircraft is at {}, {}", lat, lon);
//! }
//! ```
