mindat-rs 0.2.1

//! # mindat-rs
//!
//! A Rust client library for the [Mindat API](https://api.mindat.org/).
//!
//! Mindat is the world's largest open database of minerals, rocks, meteorites, and
//! the localities where they come from. This crate provides a type-safe, async interface
//! to access mineralogical data.
//!
//! ## Features
//!
//! - Full coverage of the Mindat API endpoints
//! - Strongly-typed request builders and response models
//! - Async/await support using tokio
//! - Pagination helpers
//! - Comprehensive error handling
//!
//! ## Quick Start
//!
//! ```no_run
//! use mindat_rs::{MindatClient, GeomaterialsQuery, Result};
//!
//! #[tokio::main]
//! async fn main() -> Result<()> {
//!     // Create a client with your API token
//!     let client = MindatClient::new("your-api-token");
//!
//!     // Search for quartz
//!     let query = GeomaterialsQuery::new()
//!         .name("quartz")
//!         .ima_approved(true);
//!
//!     let minerals = client.geomaterials(query).await?;
//!
//!     for mineral in minerals.results {
//!         println!("{}: {:?}", mineral.id, mineral.name);
//!     }
//!
//!     Ok(())
//! }
//! ```
//!
//! ## Authentication
//!
//! Most API endpoints require authentication with a Mindat API token.
//! You can obtain a token from your [Mindat account settings](https://www.mindat.org/).
//!
//! Some endpoints (like `minerals_ima`) can be accessed without authentication:
//!
//! ```no_run
//! use mindat_rs::{MindatClient, ImaMineralsQuery};
//!
//! # async fn example() -> mindat_rs::Result<()> {
//! let client = MindatClient::anonymous();
//! let minerals = client.minerals_ima(ImaMineralsQuery::new()).await?;
//! # Ok(())
//! # }
//! ```
//!
//! ## Pagination
//!
//! Most list endpoints return paginated results. Use the pagination helpers:
//!
//! ```no_run
//! use mindat_rs::{MindatClient, GeomaterialsQuery};
//!
//! # async fn example() -> mindat_rs::Result<()> {
//! let client = MindatClient::new("token");
//!
//! // Get first page
//! let query = GeomaterialsQuery::new().page(1).page_size(100);
//! let page1 = client.geomaterials(query).await?;
//!
//! // Check if there are more pages
//! if page1.has_next() {
//!     let query = GeomaterialsQuery::new().page(2).page_size(100);
//!     let page2 = client.geomaterials(query).await?;
//! }
//! # Ok(())
//! # }
//! ```
//!
//! ## Available Endpoints
//!
//! - **Geomaterials**: Search minerals, rocks, varieties, synonyms, and more
//! - **Localities**: Search mineral localities worldwide (+ name translations)
//! - **IMA Minerals**: Full search over IMA-approved mineral species (no API key required)
//! - **References**: Bibliographic references, authors, citations, and lookup tables
//! - **Occurrences**: Mineral-at-locality occurrences and aggregated statistics
//! - **Crystallography**: Crystal classes, space groups, and space-group sets
//! - **Relations**: Relationships between minerals
//! - **Geospatial**: Point/polygon queries for localities and mineral occurrences
//! - **Classification**: Dana 8th ed. and Nickel-Strunz 10th ed. systems
//! - **Locality Metadata**: Ages, statuses, and types
//! - **Exports**: Bulk data export links
//!
//! ## Note on the Mindat API (v1)
//!
//! The standalone `/countries/`, `/photocount/`, and `/locgeoregion2/` endpoints
//! were removed upstream and are no longer part of this crate. Filter localities
//! by country using [`LocalitiesQuery::country`] (e.g. `"USA"`, `"Brazil"`).
//! Note also that `/geomaterials/` and `/minerals-ima/` use the `el_inc`/`el_exc`
//! element filters and `page-size`, while `/localities/` keeps `elements_inc`/
//! `elements_exc`; the builders hide these differences.
