We know wasm is unable to return the string directly, of course we can use some libraries, but with elixir wasmex is unable to get directly, we usually pass in the address and length of the string through the memory function to get the string. Currently some languages already support multi-value return, but rust is currently unable to do multi-value return, so I used binary bit manipulation to solve this problem this is my github repository, I hope to get everyone’s advice
