Represents possible types for memory regions.

Variants

Usable

Unused memory, can be freely used by the kernel.

InUse

Memory that is already in use.

Reserved

Memory reserved by the hardware. Not usable.

AcpiReclaimable

ACPI reclaimable memory

AcpiNvs

ACPI NVS memory

BadMemory

Area containing bad memory

Kernel

Memory used for loading the kernel.

KernelStack

Memory used for the kernel stack.

PageTable

Memory used for creating page tables.

Bootloader

Memory used by the bootloader.

FrameZero

Frame at address zero.

(shouldn’t be used because it’s easy to make mistakes related to null pointers)

Empty

An empty region with size 0

BootInfo

Memory used for storing the boot information.

Package

Memory used for storing the supplied package

Trait Implementations

impl Clone for MemoryRegionType

fn clone(&self) -> MemoryRegionType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MemoryRegionType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MemoryRegionType

fn eq(&self, other: &MemoryRegionType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
