//! Builder for getting a given chapter's statistics.
//!
//! <https://api.mangadex.org/docs/swagger.html#/Statistics/get-statistics-chapter-uuid>
//!
//! This only gets statistics for a single Manga.
//!
//! # Examples
//!
//! ```rust
//! use mangadex_api_types::MangaStatus;
//! use mangadex_api::v5::MangaDexClient;
//! use uuid::Uuid;
//!
//! # async fn run() -> anyhow::Result<()> {
//! let client = MangaDexClient::default();
//!
//! // Cool Tsuma no Saa-chan chapter 25
//! let chapter_id = Uuid::parse_str("1c3a8585-8df6-46d1-af98-fa777666abf2")?;
//!
//! let chapter_stats = client
//!     .statistics()
//!     .chapter()
//!     .id(chapter_id)
//!     .get()
//!     .send()
//!     .await?;
//!
//! println!("Response: {:?}", chapter_stats);
//! # Ok(())
//! # }
//! ```
