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