ledger-rs

Communication library between Rust and Ledger Nano S/X devices

How to use

Developing an App interface

To develop an app interface it's recommended to depend on ledger-transport and make the API generic over the an Exchange (trait). An example can be found in ledger-zondax-hid tests (provided by ledger-zondax-generic) where get_device_info is independent of the transport used.

Using an App interface

To use an app interface, so when communicating with a ledger device (or emulator) the transports available are: * ledger-transport-hid * ledger-transport-zemu

How to publish to crates.io

Obviously only members of the Zondax/crates team are allowed to publish.

Afterwards, there's a correct order to publish the crates, based on the crate dependencies:

• ledger-apdu
• ledger-transport
• ledger-zondax-generic

Then, the rest of the crates can be published in any order.

``sh cargo login cargo package -p ledger-apdu cargo publish -p ledger-apdu

cargo package -p ledger-transport cargo publish -p ledger-transport

cargo package -p ledger-zondax-generic cargo publish -p ledger-zondax-generic

cargo package -p ledger-transport-hid cargo publish -p ledger-transport-hid ``
