15//! The `ink_env` utilities used to interoperate with the contract executor.
16//!
17//! Mainly provides entities to work on a contract's storage
18//! as well as high-level collections on top of those.
19//! Also provides environmental utilities, such as storage allocators,
20//! FFI to interface with FRAME contracts and a primitive blockchain
21//! emulator for simple off-chain testing.
