+# Rust Client Workspace
+
+The Rust client workspace contains the MXAccess Gateway client library, a
+test CLI, and scaffold tests for generated contract wiring. The library uses
+the shared protobuf inputs documented in
+`../../docs/client-proto-generation.md` so the Rust bindings compile against
+the same public gateway and worker contracts as the server.
+
+## Layout
+
+```text
+clients/rust/
+  Cargo.toml
+  build.rs
+  src/
+  tests/
+  crates/mxgw-cli/
+```
+
+`build.rs` reads the `.proto` files from
+`../../src/MxGateway.Contracts/Protos` and generates `tonic`/`prost` bindings
+into Cargo build output. `src/generated.rs` declares the Rust modules that
+include those generated files. `src/generated` remains reserved for checked-in
+generator output if the crate later changes to source-tree generation.
+
+## Build And Test
+
+Run the Rust workspace checks from `clients/rust`:
+
+```powershell
+cargo fmt --all --check
+cargo test --workspace
+cargo check --workspace
+```
+
+The build script uses `protoc` from `PATH` or the Windows path recorded in
+`../../docs/toolchain-links.md`.
+
+## CLI
+
+The scaffold CLI exposes version information:
+
+```powershell
+cargo run -p mxgw-cli -- version --json
+```
+
+Additional commands are implemented with the client/session wrapper work.
