Struct TransportNativeHID

pub struct TransportNativeHID { /* private fields */ }

Implementations

impl TransportNativeHID

pub fn list_ledgers(api: &HidApi) -> impl Iterator<Item = &DeviceInfo>

Get a list of ledger devices available

pub fn new(api: &HidApi) -> Result<TransportNativeHID, LedgerHIDError>

Create a new HID transport, connecting to the first ledger found

Warning

Opening the same device concurrently will lead to device lock after the first handle is closed see issue

pub fn open_device( api: &HidApi, device: &DeviceInfo, ) -> Result<TransportNativeHID, LedgerHIDError>

Open a specific ledger device

Note

No checks are made to ensure the device is a ledger device

Warning

Opening the same device concurrently will lead to device lock after the first handle is closed see issue

pub fn exchange<I>( &self, command: &APDUCommand<I>, ) -> Result<APDUAnswer<Vec<u8>>, LedgerHIDError>

where I: Deref<Target = [u8]>,

Trait Implementations

impl Exchange for TransportNativeHID

type Error = LedgerHIDError

Error defined by Transport used

type AnswerType = Vec<u8>

The concrete type containing the APDUAnswer

fn exchange<'life0, 'life1, 'async_trait, I>( &'life0 self, command: &'life1 APDUCommand<I>, ) -> Pin<Box<dyn Future<Output = Result<APDUAnswer<<TransportNativeHID as Exchange>::AnswerType>, <TransportNativeHID as Exchange>::Error>> + Send + 'async_trait>>

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

Send a command with the given transport and retrieve an answer or a transport error
