Struct MappedPageBox 

pub struct MappedPageBox { /* private fields */ }

A range of pages that is mapped for as long as this box is alive.

Implementations

impl MappedPageBox

pub fn new( layout: PageLayout, flags: PageTableEntryFlags, ) -> Result<Self, AllocError>

Allocates the pages and frames described by layout and maps them.

pub unsafe fn map_phys( phys_addr: PhysAddr, layout: PageLayout, flags: PageTableEntryFlags, ) -> Result<Self, AllocError>

Allocates the pages described by layout and maps them to phys_addr.

Safety

• The frames at phys_addr must not be deallocated while the returned box is alive.

pub fn pages(&self) -> &PageRange

Trait Implementations

impl Drop for MappedPageBox

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
