Struct CompactPtr 

pub struct CompactPtr<T: CompactRepr> { /* private fields */ }

Implementations

impl<T: CompactRepr> CompactPtr<T>

pub fn is_null(self) -> bool

pub unsafe fn as_ref(self) -> Option<Compact<T>>

Returns the element the pointer references, or None if it is null.

Safety

If non-null, self.packed must point to valid Store<T> storage (or, for a direct pointer, to a live T) and self.index must address an initialized element within it. The caller must ensure the backing storage remains live while the returned value is used.

pub unsafe fn offset(self, count: isize) -> CompactPtr<T>

Produces a pointer offset by count elements (analogous to pointer::offset).

Safety

The resulting index (self.index + count) must be in bounds or one past the end of the same allocated backing storage.

pub unsafe fn add(self, count: usize) -> CompactPtr<T>

Produces a pointer advanced by count elements (analogous to pointer::add).

Safety

The resulting index (self.index + count) must be in bounds or one past the end of the same allocated backing storage.

pub unsafe fn sub(self, count: usize) -> CompactPtr<T>

Produces a pointer moved back by count elements (analogous to pointer::sub).

Safety

count must not exceed self.index; the resulting index must be in bounds of the same allocated backing storage.

pub unsafe fn read(self) -> Compact<T>

Reads the element the pointer references (analogous to pointer::read).

Safety

self.packed must point to valid Store<T> storage (or, for a direct pointer, to a live T) and self.index must address an initialized element within it.

impl<T: CompactRepr> CompactPtr<T>

pub fn as_mut_ptr(&self) -> CompactPtrMut<T>

Direct pointers convert to a null mutable pointer: they borrow a standalone value immutably, so there is no storage a write could legally target.
