Struct NativeTool 

pub struct NativeTool { /* private fields */ }

A native (in-memory) tool implemented as a Rust async function

Native tools execute directly in the runtime process with no IPC overhead. They are defined as async closures that accept parameters and return results.

Implementations

impl NativeTool

pub fn new<F, Fut>( name: impl Into<String>, description: impl Into<String>, input_schema: JsonValue, executor: F, ) -> Self

where F: Fn(HashMap<String, JsonValue>) -> Fut + Send + Sync + 'static, Fut: Future<Output = ToolExecutionResult> + Send + 'static,

Create a new native tool

Arguments

• name - Unique identifier for the tool
• description - Human-readable description
• input_schema - JSON Schema describing input parameters
• executor - Async function that executes the tool
