Required Methods

fn sign_transaction(
    &self,
    address: &Address,
    transaction: Self::Transaction
) -> Result<Signature, Self::Error>

Sign transaction data with wallet managing address.

fn set_key_path(&self, key_path: KeyPath)

Set key derivation path for a chain.

fn update_devices(
    &self,
    device_direction: DeviceDirection
) -> Result<usize, Self::Error>

Re-populate device list Note, this assumes all devices are iterated over and updated

fn read_device(
    &self,
    usb: &HidApi,
    dev_info: &HidDeviceInfo
) -> Result<Device, Self::Error>

Read device info

fn list_devices(&self) -> Vec<WalletInfo>

List connected and acknowledged wallets

fn list_locked_devices(&self) -> Vec<String>

List locked wallets This may be moved if it is the wrong assumption, for example this is not supported by Ledger Then this method return a empty vector

fn get_wallet(&self, address: &Address) -> Option<WalletInfo>

Get wallet info.

fn get_address(
    &self,
    device: &HidDevice
) -> Result<Option<Address>, Self::Error>

Generate ethereum address for a Wallet

fn open_path<R, F>(&self, f: F) -> Result<R, Self::Error> where
    F: Fn() -> Result<R, &'static str>, 

Open a device using device path Note, f - is a closure that borrows HidResult HidDevice is in turn a type alias for a c_void function pointer For further information see: * https://github.com/paritytech/hidapi-rs * https://github.com/rust-lang/libc
