Struct NoOpObserver 

pub struct NoOpObserver {}

Trait Implementations

impl CompilerObserver for NoOpObserver

fn observe_compiled_toplevel(&mut self, _: &Rc<Lambda>)

Called when the compiler finishes compilation of the top-level of an expression (usually the root Nix expression of a file).

fn observe_compiled_lambda(&mut self, _: &Rc<Lambda>)

Called when the compiler finishes compilation of a user-defined function.

fn observe_compiled_thunk(&mut self, _: &Rc<Lambda>)

Called when the compiler finishes compilation of a thunk.

impl Default for NoOpObserver

fn default() -> NoOpObserver

Returns the “default value” for a type.

impl RuntimeObserver for NoOpObserver

fn observe_enter_bytecode_frame( &mut self, _arg_count: usize, _: &Rc<Lambda>, _call_depth: usize, )

Called when the runtime enters a new bytecode frame.

fn observe_exit_bytecode_frame(&mut self, _frame_at: usize, _stack: &[Value])

Called when the runtime exits a bytecode frame.

fn observe_suspend_bytecode_frame(&mut self, _frame_at: usize, _stack: &[Value])

Called when the runtime suspends a bytecode frame.

fn observe_enter_generator( &mut self, _frame_at: usize, _name: &str, _stack: &[Value], )

Called when the runtime enters a generator frame.

fn observe_exit_generator( &mut self, _frame_at: usize, _name: &str, _stack: &[Value], )

Called when the runtime exits a generator frame.

fn observe_suspend_generator( &mut self, _frame_at: usize, _name: &str, _stack: &[Value], )

Called when the runtime suspends a generator frame.

fn observe_generator_request(&mut self, _name: &str, _msg: &VMRequest)

Called when a generator requests an action from the VM.

fn observe_tail_call(&mut self, _frame_at: usize, _: &Rc<Lambda>)

Called when the runtime replaces the current bytecode frame for a tail call.

fn observe_enter_builtin(&mut self, _name: &'static str)

Called when the runtime enters a builtin.

fn observe_exit_builtin(&mut self, _name: &'static str, _stack: &[Value])

Called when the runtime exits a builtin.

fn observe_execute_op(&mut self, _ip: CodeIdx, _: &Op, _: &[Value])

Called when the runtime begins executing an instruction. The provided stack is the state at the beginning of the operation.
