Operations Supported

• Jumps: jump, jump_if_true, jump_if_false

• Exception Handling: throw, try_catch, finally

• Jumps: Modify the program counter to change execution flow
• Function Calls: Set up new execution context with arguments
• Returns: Restore previous execution context
• Exception Handling: Manage try-catch-finally blocks

Usage

use jetcrab::vm::executor::instruction_handlers::ControlFlowHandler;
use jetcrab::vm::executor::traits::{StackOperations, VariableManager};

let mut stack = MyStack::new();
let mut registers = MyRegisters::new();
let mut frame = MyFrame::new();

ControlFlowHandler::jump(&mut stack, &mut registers, 100)?;
