Array Host function

[ezenkico]

I was hoping I could get some help on this.

I'm trying to pass an array of bytes into a host function and I can't seem to find a solution.

I looked into using a WasmPtr but I can't get a MemoryView into the function.

Here is my code.
`
use wasmer::{Store, Module, imports, Instance, Function, FunctionEnvMut, FunctionEnv, WasmPtr, Memory, MemoryView, TypedFunction};

fn alert(_: FunctionEnvMut, m: &MemoryView, s: WasmPtr, len: u32){
match s.read_utf8_string(m, len) {
Ok(s) => println!("{s}"),
Err(e) => println!("Error: {e}")
}
}

#[derive(Clone)]
struct MyEnv{
}

fn wasm_test() -> Result<(), Box>{
let mut store = Store::default();

let module = Module::from_file(&store, "./hello_wasm.wasm")?;

let env = FunctionEnv::new(&mut store, MyEnv{});

let imported_objects = imports! {
    "env" => {
        "alert" => Function::new_typed_with_env(&mut store, &env, alert),
    }
};

let instance = Instance::new(&mut store, &module, &imported_objects)?;

let run_func: TypedFunction<(), ()> = instance.exports.get_typed_function(&mut store, "greet")?;

run_func.call(&mut store)?;

Ok(())

}
`

If someone could help me out, that would be great.

Thanks
