Struct Frame

pub struct Frame {
    pub name: String,
    pub current_store: Rc<RefCell<Store>>,
    /* private fields */
}

Fields

name: String

current_store: Rc<RefCell<Store>>

Implementations

impl Frame

pub fn new( caller_position: usize, name: &str, parent_store: Option<&Rc<RefCell<Store>>>, ) -> Frame

Constructs a new frame. A Frame maintains the caller’s position, along with its name. In the future, it will maintain local variables and any parameters passed in.

Arguments

caller_position - The position where this frame was called or entered. name - The name of this frame.

pub fn find(&self, name: &str, pos: usize) -> Result<Rc<Value>, Error>

pub fn define(&mut self, name: &str, value: Rc<Value>)

pub fn get_caller_position(&self) -> usize

This function gets the position of the caller of this frame.

Trait Implementations

impl Debug for Frame

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Frame

fn eq(&self, other: &Frame) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
