//! Crate providing allocator support for all Wasm compilations of ink! smart contracts.
//!
//! The default allocator is a bump allocator whose goal is to have a small size footprint. If you
//! are not concerned about the size of your final Wasm binaries you may opt into using the more
//! full-featured `wee_alloc` allocator by activating the `wee-alloc` crate feature.

#![cfg_attr(not(feature = "std"), no_std)]
#![cfg_attr(not(feature = "std"), feature(alloc_error_handler, core_intrinsics))]

// We use `wee_alloc` as the global allocator since it is optimized for binary file size
// so that contracts compiled with it as allocator do not grow too much in size.
