Expand description

A regular tool — called once, returns a result.

§Examples

use async_trait::async_trait;
use gemini_adk_rs::tool::ToolFunction;
use gemini_adk_rs::error::ToolError;

struct MyTool;

#[async_trait]
impl ToolFunction for MyTool {
    fn name(&self) -> &str { "my_tool" }
    fn description(&self) -> &str { "Does something useful" }
    fn parameters(&self) -> Option<serde_json::Value> { None }
    async fn call(&self, args: serde_json::Value) -> Result<serde_json::Value, ToolError> {
        Ok(serde_json::json!({"status": "ok"}))
    }
}
