Struct BuddyBlock 

pub struct BuddyBlock {
    pub base: u64,
    pub order: u32,
    pub free: bool,
}

Buddy block model for buddy system verification

Fields

base: u64

Base address (frame-aligned)

order: u32

Order: block covers 2^order frames

free: bool

Whether this block is free

Implementations

impl BuddyBlock

pub fn frame_count(&self) -> u64

Size of this block in frames

pub fn byte_size(&self) -> u64

Size of this block in bytes

pub fn buddy_base(&self) -> u64

Get the buddy block’s base address

pub fn split(&self) -> Option<(BuddyBlock, BuddyBlock)>

Split this block into two halves (returns left, right)

pub fn coalesce(&self, other: &BuddyBlock) -> Option<BuddyBlock>

Coalesce two buddy blocks into one (if they are buddies)

Trait Implementations

impl Clone for BuddyBlock

fn clone(&self) -> BuddyBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuddyBlock

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

Formats the value using the given formatter.

impl PartialEq for BuddyBlock

fn eq(&self, other: &BuddyBlock) -> 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.
