Native HID transport for Ledger Nano hardware wallets

Implementations

impl TransportNativeHID

pub fn open_all_devices() -> Result<Vec<Self>, NativeTransportError>

Open all ledger devices.

pub fn new() -> Result<Self, NativeTransportError>

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 get_manufacturer_string(&self) -> Option<String>

Get manufacturer string. Returns None on error, or on no string.

pub fn exchange(&self, command: &APDUCommand) -> Result<APDUAnswer, LedgerError>

Exchange an APDU with the device. The response data will be written to answer_buf, and a APDUAnswer struct will be created with a reference to answer_buf.

It is strongly recommended that you use the APDUAnswer api instead of reading the raw answer_buf response.

If the method errors, the buf may contain a partially written response. It is not advised to read this.
