The Rust subsystem in stellar-core integrates with C++ using a Foreign Function Interface (FFI) bridge built with the `cxx` crate. This mechanism safely manages data passing and interoperability between the two languages.

Key components of the stellar-core Rust subsystem include Soroban host invocation, fee computation, and logging modules. These modules handle the core logic for executing smart contracts and managing transaction costs.

Error handling across the C++/Rust FFI boundary involves specific strategies to ensure errors are managed safely when passing data between the C++ and Rust environments. The `cxx` crate facilitates these secure interactions.

The Soroban host architecture in stellar-core is designed to support multi-protocol execution. This architecture enables the Rust subsystem to invoke and manage smart contract operations across different protocol versions.

Yes, you can review a technical summary of the Rust subsystem to understand its dependencies and architecture. This provides a token-efficient overview of the FFI bridge, data flow, and module responsibilities without reading the source code.
