Macro guest_bindgen 

guest_bindgen!() { /* proc-macro */ }

Create the hyperlight_guest_init() function (which should be called in hyperlight_main()) for the wasm component type in the file passed in (or $WIT_WORLD, if nothing is passed in). This function registers Hyperlight functions for component exports (which are implemented by calling into the trait provided) and implements the relevant traits for a trivial Host type (by calling into the Hyperlight host).
