Basic Usage

use gemini_rust::{Gemini, Message, Role, Content};
use tokio;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let api_key = std::env::var("GEMINI_API_KEY")?;
    let client = Gemini::new(&api_key);
    
    let response = client.generate_content()
        .with_system_prompt("You are a helpful assistant.")
        .with_user_message("Hello, how are you?")
        .execute()
        .await?;
    
    println!("Response: {}", response.text());
    
    Ok(())
}

Using Google Search Tool

use gemini_rust::{Gemini, Tool};
use tokio;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let api_key = std::env::var("GEMINI_API_KEY")?;
    let client = Gemini::new(&api_key);
    
    // Create a Google Search tool
    let google_search_tool = Tool::google_search();
    
    let response = client.generate_content()
        .with_user_message("What is the current Google stock price?")
        .with_tool(google_search_tool)
        .execute()
        .await?;
    
    println!("Response: {}", response.text());
    
    Ok(())
}
