Write wasm using rust with wasm-pack and wasm-bindgen tools. But wasm-bindgen will rename export function name using shorthash.

for example:

#[wasm_bindgen]
extern "C" {
    fn alert();
}

this code will rename like this in wasm: (func $import0 (import "wbg" "__wbg_alert_2de8bdec59d2582f"))

I don't know exactly all the export function names.
Pull this request to support find import name with custom function callback.
