//! # scix-client
//!
//! A Rust client for the SciX (formerly NASA ADS) API.
//!
//! Provides:
//! - **Library**: Async API client for search, export, metrics, libraries, and more
//! - **CLI**: `scix` binary for terminal use (includes `scix serve` for MCP)
//!
//! ## Quick Start
//!
//! ```no_run
//! # async fn example() -> scix_client::error::Result<()> {
//! use scix_client::SciXClient;
//!
//! // Create client from SCIX_API_TOKEN (or ADS_API_TOKEN) environment variable
//! let client = SciXClient::from_env()?;
//!
//! // Search for papers
//! let results = client.search("author:\"Einstein\" year:1905", 10).await?;
//! for paper in &results.papers {
//! println!("{} ({}) - {}", paper.title, paper.year.unwrap_or(0), paper.bibcode);
//! }
//!
//! // Export as BibTeX
//! let bibtex = client.export_bibtex(&["2023ApJ...123..456A"]).await?;
//! println!("{}", bibtex);
//! # Ok(())
//! # }
//! ```
//!
//! ## Query Builder
//!
//! ```
//! use scix_client::QueryBuilder;
//!
//! let query = QueryBuilder::new()
//! .author("Weinberg")
//! .and()
//! .title("cosmological constant")
//! .and()
//! .property("refereed")
//! .build();
//! ```
