Struct StackManager

pub struct StackManager { /* private fields */ }

Concrete implementation of stack operations for the VM

Wraps the low-level Stack and provides high-level stack management functionality for the execution engine.

Implementations

impl StackManager

pub fn new() -> Self

Creates a new stack manager with an empty stack

Initializes the stack manager with a fresh, empty stack ready for VM operations.

pub fn stack(&self) -> &Stack

Gets read-only access to the underlying stack

Provides access to the stack for inspection and debugging without allowing modifications.

pub fn stack_mut(&mut self) -> &mut Stack

Gets mutable access to the underlying stack

Provides direct access to the stack for advanced operations and testing purposes.
