Macro wasm_plugin_guest_derive::import_functions

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

Import functions from the host program. The function’s arguments an return type must all be serializable. Several functions can be imported at once by listing their signatures seperated by ;

import_functions! {
    fn my_function();
    fn my_other_function(s: String) -> Vec<u8>;
}

The macro creates a safe wrapper function using the given name which can be called in the plugin code. The actual imported function, which normal code will never need to access, will have a mangled name: wasm_plugin_imported__ORIGINAL_NAME and is only intended to be called by by host code using wasm_plugin_host
