//! # The Scrypto Standard Library
//!
//! The Scrypto Standard Library is the foundation of Scrypto blueprints, a
//! set of minimal and shared abstractions on top of Radix Engine. It enables
//! asset-oriented programming for feature-rich DeFi dApps.
//!
//! If you know the name of what you're looking for, the fastest way to find
//! it is to use the <a href="#" onclick="focusSearchBar();">search
//! bar</a> at the top of the page.
