Object

The Object module in the Vondel language is designed to handle various types of objects used in the language, including integers, booleans, return values, null values, and functions. It provides a Object enum with associated data for each object type. The module defines methods to inspect objects and retrieve their string representation. The Object enum implements the Debug, PartialEq, and Clone traits for debugging, equality comparison, and cloning, respectively. Additionally, it provides a type_as_string() method to retrieve the type of the object as a string for error handling.

Object Enum

The Object enum represents the different types of objects in the Vondel language. It has the following variants:

• Integer(i64): Represents an integer value.
• Boolean(bool): Represents a boolean value.
• ReturnValue(Box<Object>): Represents a return value from a function.
• Null: Represents a null value.
• Function { params: Vec<Expression>, body: StatementType, env: Rc<RefCell<Environment>> }: Represents a function object, storing the function's parameters, body, and environment.

Object Methods

The Object module provides the following methods:

• inspect() -> String: Returns a string representation of the object.
• type_as_string() -> &'static str: Returns the type of the object as a string for error handling.

Display Formatting

The Object enum implements the fmt::Display trait to provide a formatted string representation for display purposes. The Display implementation formats the object based on its variant, converting it to a string representation.

#![allow(unused)]
fn main() {
impl fmt::Display for Object {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        // Format the object based on its variant
        // ...
    }
}
