examples: New app to build Rust with Cargo Build Rust applictions with cargo is the most commn way, and it's more easy to cooporate with Rust ecosystem. This example shows how to use cargo to build a simple hello world application. And please notice that you need to install nighly version of rustc to support this feature, any version after https://github.com/rust-lang/rust/pull/127755 is merged, can use NuttX as cargo target directly. Build ----- To build hello_rust_cargo application, you can use any target that based on RISCV32IMAC, for example: ``` cmake -B build -DBOARD_CONFIG=rv-virt:nsh -GNinja . ``` And disable ARCH_FPU in menuconfig, since the hard coded target triple in this demo is `riscv32imac`.

apps/rust: Add dependencies for Rust cargo in make builds Add a Rust make helper that collects crate input files, and use it for the Rust hello and slint examples. This makes the generated Rust static libraries depend on the crate sources, manifests, build scripts. Hook the libraries into both context and all, so re-running make after editing Rust inputs rebuilds the crate. Signed-off-by: Shoji Tokunaga <toku@mac.com>

examples/rust: Avoid the infinite loop on sim for hello_rust_cargo On the sim target (Windows/macOS/Linux), hello_rust_cargo_main() ended with an infinite `loop {}` that never returned control to NSH, so the example could not exit and the shell prompt hung. Introduce a Cargo `sim` feature that is enabled only when CONFIG_ARCH_SIM is set, and use it to compile out the trailing infinite loop and return 0 instead. Other embedded targets keep the original looping behavior. Signed-off-by: Shoji Tokunaga <toku@mac.com>
