Rust quickstart

1. Install hypertune

Once you have a Rust application ready, install Hypertune's Rust crate and the Serde crate:

cargo add hypertune serde

2. Install the Hypertune CLI

Run the following command to install the CLI

curl -fsSL https://app.hypertune.com/install-cli.sh | sh

Alternatively, you can download the Hypertune CLI for your system:

• Mac (x86_64)

• Mac M1 / M2 (aarch64)

• Linux (x86_64)

• Windows (x86_64)

Then:

• Put it somewhere accessible via your PATH

• Add execute permissions to it with chmod +x hypertune

• Right-click to open it

3. Generate the client

Generate a type-safe client to access your flags by running:

hypertune generate --language rust --output-file-dir src --token <token> 

Replace <token> with your main project token which you can find in the Settings tab of your project.

4. Use the client

mod hypertune;

fn main() {
    let root_node = hypertune::create_source(hypertune::VariableValues {}, None)
        .unwrap()
        .root(hypertune::RootArgs {
            context: hypertune::Context {
                environment: hypertune::Environment::DEVELOPMENT,
                user: hypertune::User {
                    id: "test_id".to_string(),
                    name: "Test".to_string(),
                    email: "[email protected]".to_string(),
                },
            },
        });
    root_node.wait_for_initialization();
    
    let example_flag = root_node.exampleFlag().get(false);
    
    root_node.close();
}

Next steps

Now you can update the logic for exampleFlag from the Hypertune UI without updating your code or waiting for a new build, deployment, app release, or service restart.

To add a new flag, create it in the Hypertune UI then regenerate the client.
