- * Memory hooks have two purposes:
- * 1. To allow reads and writes to a region of memory to be intercepted. This is used to implement
- * texture forwarding and memory breakpoints for debugging.
- * 2. To allow for the implementation of MMIO devices.
- *
- * A hook may be mapped to multiple regions of memory.
- *
- * If a std::nullopt or false is returned from a function, the read/write request is passed through
- * to the underlying memory region.
