1//! Standalone environment for WebAssembly using Cranelift. Provides functions to translate
2//! `get_global`, `set_global`, `memory.size`, `memory.grow`, `call_indirect` that hardcode in
3//! the translation the base addresses of regions of memory that will hold the globals, tables and
4//! linear memories.
