Struct lualite::bytecode::operand::InstructionPointer

#[repr(transparent)]
pub struct InstructionPointer(pub u16);

An index into the bytecode array

A 16 bit unsigned integer taking up both source operand bytes. It is used by the jump family of instructions under misc.

Instruction pointers are always an absolute offset from the beginning of a function’s bytecode. Setting a jump’s instruction pointer target to be outside the bounds of the function’s bytecode will cause a RuntimeError in the VirtualMachine. Runtime errors are safe and recoverable by host code, but hault client code running in a virtual machine when they are encountered.
