Struct Slot

pub struct Slot { /* private fields */ }

A slot for an object in active memory. All unique combinations of an object ID and Protections are given a slot. The exact slot locations may be reused. Typically, slots are reference counted, and when dropped, release the slot for reuse. The object may or may not be unmapped immediately following the slot’s drop.

Implementations

impl Slot

pub fn new_from_handle(handle: ObjectHandle) -> Result<Self, ObjectInitError>

pub fn runtime_handle(&self) -> &ObjectHandle

pub fn slot_number(&self) -> usize

pub fn id(&self) -> ObjID

Get the ID of the object in this slot.

pub fn prot(&self) -> Protections

Get the protections of this slot.

pub fn vaddr_base(&self) -> usize

Get the vaddr of this slot’s object base.

pub fn vaddr_null(&self) -> usize

Get the vaddr of this slot’s object’s null page.

pub fn vaddr_meta(&self) -> usize

pub fn raw_lea<P>(&self, off: usize) -> *const P

Perform a raw load-effective-address for an offset into a slot.

pub fn raw_lea_mut<P>(&self, off: usize) -> *mut P

Perform a raw load-effective-address for an offset into a slot.

pub unsafe fn get_fote_unguarded(&self, idx: usize) -> *mut FotEntry
