pub fn handle(&self) -> BlockHandle

Returns the underlying block handle.

pub fn base(&self) -> PhysAddr

Returns the base physical address of the block.

pub fn order(&self) -> u8

Returns the buddy order of the block.

pub(crate) fn from_handle(handle: BlockHandle) -> Self

Creates a typed block from a raw handle.

impl PhysBlock<BuddyReserved>

pub(crate) fn into_exclusive(self) -> PhysBlock<Exclusive>

Transitions a reserved block into exclusive ownership.

impl PhysBlock<Exclusive>

pub(crate) fn into_mapped(self) -> PhysBlock<MappedExclusive>

Marks the block as mapped while remaining exclusive.

pub(crate) fn into_released(self) -> PhysBlock<Released>

Releases the block to the buddy-facing state.

impl PhysBlock<MappedExclusive>

pub(crate) fn into_shared(self) -> PhysBlock<MappedShared>

Transitions a mapped exclusive block into a shared mapped block.

pub(crate) fn into_unmapped(self) -> PhysBlock<Exclusive>

Transitions a mapped exclusive block back to an unmapped exclusive block.

impl PhysBlock<MappedShared>

pub(crate) fn into_exclusive_mapped(self) -> PhysBlock<MappedExclusive>

Transitions a shared mapped block back to a mapped exclusive block.

pub(crate) fn still_shared(self) -> PhysBlock<MappedShared>

Rebuilds the shared typed handle after an ownership-layer check.

impl PhysBlock<Released>

pub(crate) fn into_handle(self) -> BlockHandle
