Dennis Zhang (Nov 18 2022 at 03:38): Dennis Zhang (Nov 18 2022 at 03:38):How to pass a string into wasm then manipulate it, then return with a new string defined in wasm? is there any example for this?
Dennis Zhang (Nov 18 2022 at 07:09):can I pass a tcp connection to wasm module and handle it as a File? If I implement the WasiFile trait for it
Lann Martin (Nov 18 2022 at 14:27):As of wasmtime 1.0 you don't even need to implement WasiFile: https://docs.rs/wasmtime-wasi/2.0.2/wasmtime_wasi/sync/struct.WasiCtxBuilder.html#method.preopened_socket
Dennis Zhang (Nov 19 2022 at 08:00):what does the fd in the function mean? the fd of the opened socket?
bjorn3 (Nov 19 2022 at 09:27):The fd that will be assigned to the socket in the guest.
Dennis Zhang (Nov 19 2022 at 10:20):okay thanks, I will try it out

I am quite confused on this function, the Into<Socket> requires cap_std::net::TcpStream, while that is based on non-wasi feature, which is kind of confusing, can you possibly explain it to me? thanks
Dennis Zhang (Nov 19 2022 at 14:49):Can anyone show me a very simple example of that function usage? I really don't know how to handle it correctly.
