Struct App 

pub struct App<T, S, C = ()> { /* private fields */ }

Implementations

impl<T, S, C> App<T, S, C>

where T: TrussedClient, S: StatusBytes, C: Config,

pub fn load_config<F: Filestore>( client: T, filestore: &mut F, data: Data, status: S, ) -> Result<Self, (T, ConfigError)>

Create an admin app instance, loading the configuration from the filesystem.

pub fn migrate<F: Filestore>( &mut self, to_version: u32, store: impl Store, filestore: &mut F, ) -> Result<(), ConfigError>

pub fn with_default_config(client: T, data: Data, status: S) -> Self

Create an admin app instance without the configuration mechanism, using the default config values.

This is only intended for debugging, testing and example code. In production, App::load_config should be used.

pub fn config(&self) -> &C

pub fn config_mut(&mut self) -> &mut C

pub fn save_config_filestore<F: Filestore>( &mut self, filestore: &mut F, ) -> Result<(), ConfigError>

pub fn status(&self) -> &S

pub fn status_mut(&mut self) -> &mut S

Trait Implementations

impl<T, S, C> App for App<T, S, C>

where T: TrussedClient, S: StatusBytes,

fn aid(&self) -> Aid

impl<T, S, C> App for App<T, S, C>

where T: TrussedClient, S: StatusBytes, C: Config,

fn select( &mut self, _interface: Interface, _apdu: CommandView<'_>, _reply: &mut VecView<u8>, ) -> Result

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 VecView<u8>, ) -> Result

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

impl<T, S, C> App<'static> for App<T, S, C>

where T: TrussedClient, S: StatusBytes, C: Config,

fn commands(&self) -> &'static [HidCommand]

Define which CTAPHID commands to register to.

fn call( &mut self, command: HidCommand, input_data: &[u8], response: &mut BytesView, ) -> Result<(), Error>

Application is called here when one of it’s register commands occurs. Application must put response in @message, or decide to return an error.

fn interrupt(&self) -> Option<&'static InterruptFlag>

Get access to the app interrupter
