Enum MemoryZone 

pub enum MemoryZone {
    Dma,
    Normal,
    High,
}

Memory zone for frame allocation

Variants

Dma

DMA zone (0-16MB on x86)

Normal

Normal zone (16MB-4GB on 32-bit, all memory on 64-bit)

High

High memory zone (>4GB on 32-bit, unused on 64-bit)

Implementations

impl MemoryZone

pub fn frame_range(&self) -> (FrameNumber, FrameNumber)

Get the frame range for this zone on the current architecture

pub fn contains(&self, frame: FrameNumber) -> bool

Check if a frame belongs to this zone

pub fn for_frame(frame: FrameNumber) -> Self

Get the appropriate zone for a frame number

Trait Implementations

impl Clone for MemoryZone

fn clone(&self) -> MemoryZone

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryZone

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

Formats the value using the given formatter.

impl PartialEq for MemoryZone

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

Tests for self and other values to be equal, and is used by ==.

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

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