Detailed Description

Implements the OP_RUST_SET_EXIT opcode (conditional build).

Pops an integer exit code and delegates to a Rust helper to store it into vm.exit_code. Pushes Nil afterwards. When Rust support is disabled, the argument is still popped/freed, a runtime error is raised, and Nil is pushed to maintain stack discipline.

OP_RUST_SET_EXIT

case OP_RUST_SET_EXIT

OP_RUST_SET_EXIT: (code:int) -> Nil

Behavior (FUN_WITH_RUST=ON):

• Expects an integer on the stack (provided by previous opcodes).
• Calls fun_op_rset_exit(vm) which pops the int and writes vm->exit_code.
• Pushes Nil.

Behavior (FUN_WITH_RUST=OFF):

• Pops and frees one value to preserve stack discipline.
• Raises a runtime error indicating missing Rust support.
• Pushes Nil.
