Struct Store

pub struct Store { /* private fields */ }

Implementations

impl Store

pub fn new(parent_store: Option<Rc<RefCell<Store>>>) -> Store

Creates a new Store.

Arguments

parent_store - The parent of this store. This maintains all of the variables defined in a higher scope.

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

This function defines a new variable. The variable will be bound to the scope containing this store. This function will override any existing value of a previously defined value.

Arguments

name - The name of the variable. value - The value of the variable.

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

This function gets the value of a variable. If the variable does not exist, then an error is reported.

Arguments

name - The name of the variable. pos - The position where this operation was called.

Trait Implementations

impl Debug for Store

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

Formats the value using the given formatter.

impl PartialEq for Store

fn eq(&self, other: &Store) -> 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.
