Rust Low-level bindings to the Ledger C SDK

Provides access to low-level APIs to the operating system of Ledger devices.

Build

Depending on the target (--target nanos, --target nanox, ...), this crate will git clone the appropriate branch (API_LEVEL_x) of the C SDK and compile the subset of files necessary for the Rust SDK to work.

To use an already-cloned C SDK, you can pass its path through the environment variable LEDGER_SDK_PATH=/path/to/c_sdk or through cargo's --config flag:

cargo build --target nanosplus --config env.LEDGER_SDK_PATH="../ledger-secure-sdk/"
