}

Fields

rng: &'a RNG

apps: Grant<App>

Trait Implementations

impl<'a, RNG: RNG> Client for SimpleRng<'a, RNG>

fn randomness_available(
    &self,
    randomness: &mut Iterator<Item = u32>
) -> Continue

Called by the (RNG)[trait.RNG.html] when there are one or more random numbers available

impl<'a, RNG: RNG> Driver for SimpleRng<'a, RNG>

fn allow(
    &self,
    appid: AppId,
    allow_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.

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,
    data: usize,
    _: usize,
    appid: AppId
) -> ReturnCode

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