Running the Rust Demos

You can run the examples either by going into folder or into the rust sub-folder and use cargo run, for example:

cd demos/printerdemo/rust
cargo run --release

or you can run them from anywhere in the Cargo workspace by name:

cargo run --release --bin printerdemo

---

Wasm builds

In order to make the wasm build of the example, you first need to edit the Cargo.toml files to uncomment the line starting with #wasm# (or use the sed line bellow) You can then use wasm-pack (which you may need to obtain with cargo install wasm-pack). This will generate the wasm in the ./pkg directory, which the index.html file will open. Since wasm files cannot be served from file:// URL, you need to open a wab server to serve the content

cd demos/printerdemo/rust
sed -i "s/^#wasm# //" Cargo.toml
wasm-pack build --release --target web
python3 -m http.server

Running the C++ Examples

• When compiling Slint from sources: If you follow the C++ build instructions, this will build the C++ examples as well by default
• From installed binary packages: Simply run cmake in one of the example directory containing a CMakeLists.txt

mkdir build && cd build
cmake -GNinja -DCMAKE_PREFIX_PATH="<path to installed>" ..
cmake --build .

Running the Node Examples

You can run the examples by going into the node sub-folder and use pnpm, for example:

cd demos/printerdemo/node
pnpm install
pnpm start
