Handler for function calls (user-defined, builtin, external)

Required Methods

fn call_function( &mut self, context: &mut Context, func: JsonnetValue, args: Vec<JsonnetValue>, ) -> Result<JsonnetValue>

Call a function with given arguments

fn is_builtin_function(&self, name: &str) -> bool

Check if a function name refers to a builtin function

fn call_builtin_function( &mut self, context: &mut Context, name: &str, args: Vec<JsonnetValue>, ) -> Result<JsonnetValue>

Call a builtin function

fn is_external_function(&self, name: &str) -> bool

Check if a function name refers to an external function

fn call_external_function( &mut self, context: &mut Context, name: &str, args: Vec<JsonnetValue>, ) -> Result<JsonnetValue>

Call an external function (HTTP, AI API, system commands, etc.)
