Trait wasmer::HostFunction

pub trait HostFunction<T, Args, Rets, Kind>
where
    Args: WasmTypeList,
    Rets: WasmTypeList,
    Kind: HostFunctionKind,
{
    // Required method
    fn function_callback(&self) -> *const VMFunctionBody;

    // Provided method
    fn call_trampoline_address() -> VMTrampoline { ... }
}
