### Implement BenchSuite Trait for Custom Load Testing

Source: https://github.com/wfxr/rlt/blob/main/README.md

This Rust code defines a custom `HttpBench` struct using `clap::Parser` to handle command-line arguments, including a target URL and embedded `BenchCli` options. It then implements the `BenchSuite` trait, specifying `Client` as the worker state and defining the asynchronous `bench` method. The `bench` method performs an HTTP GET request, measures the duration, status, and bytes received, and returns an `IterReport` for each iteration.

```Rust
#[derive(Parser, Clone)]
pub struct HttpBench {
    /// Target URL.
    pub url: Url,

    /// Embed BenchCli into this Opts.
    #[command(flatten)]
    pub bench_opts: BenchCli,
}

#[async_trait]
impl BenchSuite for HttpBench {
    type WorkerState = Client;

    async fn state(&self, _: u32) -> Result<Self::WorkerState> {
        Ok(Client::new())
    }

    async fn bench(&mut self, client: &mut Self::WorkerState, _: &IterInfo) -> Result<IterReport> {
        let t = Instant::now();
        let resp = client.get(self.url.clone()).send().await?;
        let status = resp.status().into();
        let bytes = resp.bytes().await?.len() as u64;
        let duration = t.elapsed();
        Ok(IterReport { duration, status, bytes, items: 1 })
    }
}
```

### Run rlt Load Test from Main Function

Source: https://github.com/wfxr/rlt/blob/main/README.md

This Rust code snippet illustrates the main function for a load test application using rlt. It uses `tokio::main` for asynchronous execution, parses the `HttpBench` command-line arguments, and then calls `rlt::cli::run` to execute the load test using the parsed options and the custom `HttpBench` suite.

```Rust
#[tokio::main]
async fn main() -> Result<()> {
    let bs = HttpBench::parse();
    rlt::cli::run(bs.bench_opts, bs).await
}
```

### Add rlt Dependency to Cargo.toml

Source: https://github.com/wfxr/rlt/blob/main/README.md

Instructions to add the rlt crate as a dependency to your Rust project's Cargo.toml file, specifying version 0.1.1. This is the first step to integrate rlt into your project.

```TOML
[dependencies]
rlt = "0.1.1"
```
