//! VM types can be passed between the host and guest via wasm linear
//! memory.
//!
//! These are either:
//! 1. Module call types The module call inputs are passed host-to-guest.
//!
//! 2. Execution environment types The environment inputs are passed
//!    guest-to-host and outputs back from host-to-guest.
