//! The Stylus SDK.
//!
//! The Stylus SDK makes it easy to develop Solidity ABI-equivalent Stylus contracts in Rust.
//! Included is a full suite of types and shortcuts that abstract away the details of Solidity's storage layout,
//! method selectors, affordances, and more, making it easy to *just write Rust*.
//! For a guided exploration of the features, please see the comprehensive [Feature Overview][overview].
//!
//! Some of the features available in the SDK include:
//! - **Generic**, storage-backed Rust types for programming **Solidity-equivalent** smart contracts with optimal
//! storage caching.
//! - Simple macros for writing **language-agnostic** methods and entrypoints.
//! - Automatic export of Solidity interfaces for interoperability across programming languages.
//! - Powerful **primitive types** backed by the feature-rich [Alloy][alloy].
//!
//! Rust programs written with the Stylus SDK can **call and be called** by Solidity smart contracts
//! due to ABI equivalence with Ethereum programming languages. In fact, existing Solidity DEXs can list Rust
//! tokens without modification, and vice versa.
//!
