Trait App 

pub trait App: App {
    // Required methods
    fn select(
        &mut self,
        interface: Interface,
        apdu: CommandView<'_>,
        reply: &mut VecInner<u8, usize, VecStorageInner<[MaybeUninit<u8>]>>,
    ) -> Result<(), Status>;
    fn deselect(&mut self);
    fn call(
        &mut self,
        interface: Interface,
        apdu: CommandView<'_>,
        reply: &mut VecInner<u8, usize, VecStorageInner<[MaybeUninit<u8>]>>,
    ) -> Result<(), Status>;
}

An App can receive and respond APDUs at behest of the ApduDispatch.

Required Methods

fn select( &mut self, interface: Interface, apdu: CommandView<'_>, reply: &mut VecInner<u8, usize, VecStorageInner<[MaybeUninit<u8>]>>, ) -> Result<(), Status>

Given parsed APDU for select command. Write response data back to buf, and return length of payload. Return APDU Error code on error. Alternatively, the app can defer the response until later by returning it in poll().

fn deselect(&mut self)

Deselects the app. This is the result of another app getting selected. App should clear any sensitive state and reset security indicators.

fn call( &mut self, interface: Interface, apdu: CommandView<'_>, reply: &mut VecInner<u8, usize, VecStorageInner<[MaybeUninit<u8>]>>, ) -> Result<(), Status>

Given parsed APDU for app when selected. Write response data back to buf, and return length of payload. Return APDU Error code on error.
