revisit knowledge of Rust
run iroha nodes and connect to it via both `iroha_client_cli` and client app
run cbindgen on a small example: - export a function from Rust - generate C bindings with cbindgen - link this C lib from C and Java

fork the cbindgen repository
add the functionality to parse function signatures from MIR

make use of ffi_export macro to generate FFI bindings of methods and functions in iroha_client
MIR approach failed - explore other approaches
