Struct Json 

pub struct Json<T>(pub T);

Wrapper for returning serializable values as JSON tool output.

Implements From<Json<T>> for ToolOutput so it works with the #[llm_tool] macro’s .into() conversion — no Result wrapper needed for infallible serialization.

Panics

The From conversion panics if serde_json::to_string fails. This only happens with broken Serialize implementations (e.g., maps with non-string keys). For explicit error handling, use ToolOutput::json() instead.

Example

use llm_tool::{Json, ToolOutput};
use serde::Serialize;

#[derive(Serialize)]
struct Weather {
    temp: f64,
    city: String,
}

let output: ToolOutput = Json(Weather {
    temp: 72.0,
    city: "NYC".into(),
})
.into();
assert!(output.content().contains("72"));
