Struct librsnek::runtime::interpreter::InterpreterFrame

struct InterpreterFrame {
    frame: RtObject,
    stack: RefCell<List>,
    lineno: Cell<usize>,
}

Attaches extra data to a frame object which is Interpreter runtime execution

Fields

frame: RtObject

stack: RefCell<List>

lineno: Cell<usize>

Methods

impl InterpreterFrame

fn new(frame: RtObject) -> Self

Create a new frame from an RtObject. Note that there are no asserts

fn object(&self) -> &RtObject

Get the reference to the object that represents the frame.

fn stack(&self) -> Ref<List>

Get a Ref to the frame's value stack.

fn line(&self) -> usize

The most recent line number. The parser and compiler eat a lot of the

fn set_line(&self, line: usize) -> usize

Called by the interpreter to set the line of the frame

fn push_stack(&self, objref: &RtObject)

Push an object onto this frame's value stack. That object will become

fn pop_stack(&self) -> Option<RtObject>

Pop a value off of the value stack if present.

fn clear_stack(&self)

Remove all values in this frame's value stack. For use in the current
