Implementing

The native_pkcs11_traits::Backend trait must be implemented to add support for a store. Backends are registered in the exported C_GetFunctionList function. In order to register a backend, export the method from the crate. For example:

use native_pkcs11::{CKR_OK, CK_FUNCTION_LIST_PTR_PTR, CK_RV, FUNC_LIST};

#[no_mangle]
pub extern "C" fn C_GetFunctionList(function_list_ptr_ptr: CK_FUNCTION_LIST_PTR_PTR) -> CK_RV {
    // add the custom backend
    native_pkcs11_traits::register_backend(Box::new(backend::MyBackend {}));
    // assign this function to the native-pkcs11 function list C_GetFunctionList
    FUNC_LIST.C_GetFunctionList = Some(C_GetFunctionList);
    // assign the result to the output parameter
    unsafe { *function_list_ptr_ptr = &mut FUNC_LIST };
    return CKR_OK;
}
