Implementations

impl SimpleTool

pub fn new<F, Fut>( name: impl Into<String>, description: impl Into<String>, parameters: Option<Value>, handler: F, ) -> SimpleTool

where F: Fn(Value) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<Value, ToolError>> + Send + 'static,

Create a new simple function tool.

Examples

use gemini_adk_rs::tool::SimpleTool;
use serde_json::json;

let tool = SimpleTool::new(
    "greet",
    "Greet a user by name",
    Some(json!({"type": "object", "properties": {"name": {"type": "string"}}, "required": ["name"]})),
    |args| async move {
        let name = args["name"].as_str().unwrap_or("World");
        Ok(json!({"greeting": format!("Hello, {name}!")}))
    },
);
