---

name: rust-build description: Build Rust native libraries for the FFI plugin argument-hint: "[target]" disable-model-invocation: true allowed-tools: Bash(cargo *), Bash(rustup *)

Build the Rust native libraries for the keychat_rust_ffi_plugin.

Arguments

• $ARGUMENTS - Target platform: ios, android, linux, windows, macos

Prerequisites

Ensure flutter_rust_bridge codegen is installed:

cargo install flutter_rust_bridge_codegen@2.11.1

For Linux, install system dependencies:

apt install protobuf-compiler libsecret-1-dev

Target Setup and Build Commands

| Platform | Target | Setup & Build | |----------|--------|---------------| | iOS | aarch64-apple-ios | rustup target add aarch64-apple-ios && cargo build --target aarch64-apple-ios --release | | Android | aarch64-linux-android | rustup target add aarch64-linux-android && cargo build --target aarch64-linux-android --release | | Linux | x86_64-unknown-linux-gnu | rustup target add x86_64-unknown-linux-gnu && cargo build --target x86_64-unknown-linux-gnu --release | | Windows | x86_64-pc-windows-msvc | rustup target add x86_64-pc-windows-msvc && cargo build --target x86_64-pc-windows-msvc --release | | macOS | aarch64-apple-darwin | rustup target add aarch64-apple-darwin && cargo build --target aarch64-apple-darwin --release |

Workflow

1. Change to the Rust plugin directory:

   cd packages/keychat_rust_ffi_plugin/rust
   

2. If no target specified, ask which platform to build for

3. Add the rustup target if not already added:

   rustup target add <target>
   

4. Build the library:

   cargo build --target <target> --release --target-dir target
   

5. Report build success or any errors

Regenerating Dart Bindings

After modifying Rust API files, regenerate the Dart bindings:

cd packages/keychat_rust_ffi_plugin
flutter_rust_bridge_codegen generate
