//! GDELT DOC 2.0 API wire types.
//!
//! `mode=artlist&format=json` answers with a single `articles` array. GDELT
//! reports more fields than modelled here (`url_mobile`, `language`,
//! `sourcecountry`, …) — only the ones [`super::corporate::to_news_at`] maps
//! onto the canonical [`crate::models::corporate::news::News`] are kept.
//! GDELT sometimes omits a field entirely (rather than sending an empty
//! string) for older or thinly-indexed sources, so everything but `url` is
//! optional.

use serde::Deserialize;

/// The envelope returned by `mode=artlist`.

    #[serde(default)]
