Common commands for any given APP

This trait is automatically implemented for any type that implements App

Provided Methods

fn handle_response_error( response: &APDUAnswer<E::AnswerType> ) -> Result<(), LedgerAppError<E::Error>>

Handles the error response from APDU exchange.

Arguments

• response - The response from the APDU exchange.

Returns

A result indicating success or containing a specific ledger application error.

fn handle_response_error_signature( response: &APDUAnswer<E::AnswerType> ) -> Result<(), LedgerAppError<E::Error>>

Handles the error response from APDU exchange.

Arguments

• response - The response from the APDU exchange.

Returns

A result indicating success or containing a specific ledger application error.

fn get_device_info<'life0, 'async_trait>( transport: &'life0 E ) -> Pin<Box<dyn Future<Output = Result<DeviceInfo, LedgerAppError<E::Error>>> + Send + 'async_trait>>

where 'life0: 'async_trait,

Retrieve the device info

Works only in the dashboard

fn get_app_info<'life0, 'async_trait>( transport: &'life0 E ) -> Pin<Box<dyn Future<Output = Result<AppInfo, LedgerAppError<E::Error>>> + Send + 'async_trait>>

where 'life0: 'async_trait,

Retrieve the app info

Works only in app (TOOD: dashboard support)

fn get_version<'life0, 'async_trait>( transport: &'life0 E ) -> Pin<Box<dyn Future<Output = Result<Version, LedgerAppError<E::Error>>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait,

Retrieve the app version

fn send_chunks<'life0, 'life1, 'async_trait, I>( transport: &'life0 E, command: APDUCommand<I>, message: &'life1 [u8] ) -> Pin<Box<dyn Future<Output = Result<APDUAnswer<E::AnswerType>, LedgerAppError<E::Error>>> + Send + 'async_trait>>

where I: 'async_trait + Deref<Target = [u8]> + Send + Sync, Self: Send + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Stream a long request in chunks, with an option to set P2 for all chunks. This method combines the functionality of sending chunks with or without P2 set for all chunks.

Arguments

• transport - The transport layer used for communication.
• command - The initial APDU command.
• message - The message to be sent in chunks.
• set_p2_for_all - A boolean to determine if P2 should be set for all chunks.

Returns

A result containing the final APDU answer or a ledger application error.

Object Safety
