Enum ToolFunction 

pub enum ToolFunction {
    Sync(Box<dyn Fn(Value) -> Result<String> + Send + Sync>),
    Async(Box<dyn Fn(Value) -> BoxFuture<'static, Result<String>> + Send + Sync>),
}

Wrapper for tool functions (sync or async)

Tool functions receive raw JSON args and are responsible for deserializing into their expected type. The tool<T, F>() method handles this automatically by wrapping typed handlers.

Variants

Sync(Box<dyn Fn(Value) -> Result<String> + Send + Sync>)

Async(Box<dyn Fn(Value) -> BoxFuture<'static, Result<String>> + Send + Sync>)
