Struct Ptr

pub struct Ptr<T> {
    ptr: NonNull<PtrCell<T>>,
    _marker: PhantomData<PtrCell<T>>,
}

Heap-backed pointer value with one explicit level of indirection.

Fields

ptr: NonNull<PtrCell<T>>

_marker: PhantomData<PtrCell<T>>

Implementations

impl<T> Ptr<T>

pub fn new(value: T) -> Self

Allocate one new pointer payload.

pub fn new_tracked(value: T, site: &'static str) -> Self

Allocate one new pointer payload with allocation-site metadata.

pub fn borrow(&self) -> &T

Borrow the current payload immutably.

fn cell(&self) -> &PtrCell<T>

fn cell_mut(&mut self) -> &mut PtrCell<T>

fn release(&mut self)

pub fn borrow_mut(&mut self) -> &mut T

Borrow the current payload mutably.

Trait Implementations

impl<T: Clone> Clone for Ptr<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Ptr<T>

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

Formats the value using the given formatter.

impl<T> Drop for Ptr<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: PartialEq> PartialEq for Ptr<T>

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