+///
+/// After this function completes, UEFI hands over control of the hardware
+/// to the executing OS loader, which implies that the UEFI boot services
+/// are shut down and cannot be used anymore. Only UEFI configuration tables
+/// and run-time services can be used.
+///
+/// The memory map at the time of exiting boot services returned. The map is
+/// backed by a pool allocation of the given `memory_type`. Since the boot
+/// services function to free that memory is no longer available after calling
+/// `exit_boot_services`, the allocation will not be freed on drop.
+///
+/// Note that once the boot services are exited, associated loggers and
+/// allocators can't use the boot services anymore. For the corresponding
+/// abstractions provided by this crate (see the [`helpers`] module),
+/// invoking this function will automatically disable them. If the
+/// `global_allocator` feature is enabled, attempting to use the allocator
+/// after exiting boot services will panic.
+///
+/// # Safety
+///
+/// The caller is responsible for ensuring that no references to
+/// boot-services data remain. A non-exhaustive list of resources to check:
+///
+/// * All protocols will be invalid after exiting boot services. This
+///   includes the [`Output`] protocols attached to stdout/stderr. The
+///   caller must ensure that no protocol references remain.
+/// * The pool allocator is not usable after exiting boot services. Types
+///   such as [`PoolString`] which call [`free_pool`] on drop
+///   must be cleaned up before calling `exit_boot_services`, or leaked to
+///   avoid drop ever being called.
+/// * All data in the memory map marked as
+///   [`MemoryType::BOOT_SERVICES_CODE`] and
+///   [`MemoryType::BOOT_SERVICES_DATA`] will become free memory.
+///
+/// # Errors
+///
+/// This function will fail if it is unable to allocate memory for
+/// the memory map, if it fails to retrieve the memory map, or if
+/// exiting boot services fails (with up to one retry).
+///
+/// All errors are treated as unrecoverable because the system is
+/// now in an undefined state. Rather than returning control to the
+/// caller, the system will be reset.
