Struct SendConstPtr 

pub struct SendConstPtr<T>(/* private fields */);

Wrapped const raw pointer that is Send but not Sync

Implementations

impl<T> SendConstPtr<T>

pub const fn new(ptr: *const T) -> Self

Makes ptr Send

pub const fn from_address(addr: usize) -> Self

Returns a SendConstPtr from an arbitrary address. This is equivalent to casting usize as *const T

pub fn as_address(&self) -> usize

Returns the address of the pointer. This is equivalent to casting the pointer using *mut T as usize.

Note

Starting with rust 1.84.0, the pointer itself has the functions addr and expose_provenance. These functions should be used instead. They are available via the deref trait. This function is roughly equivalent to the expose_provenance function.

pub const fn null() -> Self

Makes a Send null ptr.

pub const fn cast<Y>(&self) -> SendConstPtr<Y>

Casts ptr to another data type while keeping it Send.

pub const fn inner(&self) -> *const T

Returns inner ptr which is then no longer Send.

pub const fn as_sync_const(&self) -> SyncConstPtr<T>

Makes this ptr Sync

pub const fn as_send_const(&self) -> Self

This is equivalent to .clone() and does nothing.

pub const fn as_sync_mut(&self) -> SyncMutPtr<T>

Makes this ptr Sync

Safety

ptr is also marked as mutable. Writing to immutable data is usually UB.

pub const fn as_send_mut(&self) -> SendMutPtr<T>

Makes this ptr mutable

Safety

Writing to immutable data is UB.

Trait Implementations

impl<T> Clone for SendConstPtr<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for SendConstPtr<T>

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

Formats the value using the given formatter.

impl<T> Deref for SendConstPtr<T>

type Target = *const T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> From<SendConstPtr<T>> for *const T

fn from(val: SendConstPtr<T>) -> *const T

Converts to this type from the input type.

impl<T> From<SendConstPtr<T>> for usize

fn from(val: SendConstPtr<T>) -> Self

Converts to this type from the input type.

impl<T> From<usize> for SendConstPtr<T>

fn from(value: usize) -> Self

Converts to this type from the input type.

impl<T> Hash for SendConstPtr<T>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> Ord for SendConstPtr<T>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T> PartialEq for SendConstPtr<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.

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
