Trait Implementations

impl<'a, C> Driver for UsbSyscallDriver<'a, C> where
    C: Client, 

fn subscribe(&self, subscribe_num: usize, callback: Callback) -> ReturnCode

subscribe lets an application pass a callback to the driver to be called later. This returns ENOSUPPORT if not used.

fn command(
    &self,
    command_num: usize,
    _arg: usize,
    _: usize,
    appid: AppId
) -> ReturnCode

command instructs a driver to perform some action synchronously. This returns ENOSUPPORT if not used.

fn allow(
    &self,
    app: AppId,
    minor_num: usize,
    slice: AppSlice<Shared, u8>
) -> ReturnCode

allow lets an application give the driver access to a buffer in the application's memory. This returns ENOSUPPORT if not used.
