Struct UsbTransport

Source 
pub struct UsbTransport { /* private fields */ }
Expand description

USB HID based transport

§Safety

Due to hidapi this is not thread safe an only one instance must exist in an application. If you don’t need low-level control see crate::LedgerProvider for a tokio based wrapper.
