Struct TinyPtr 

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

A tiny pointer to a mutable value of type T. As with all types of this crate, memory is allocated on the heap.

use tinypointers::TinyPtr;

let x = TinyPtr::new(42);
println!("{}", unsafe { *x.get() }); // prints 42

Implementations

impl<T> TinyPtr<T>

pub fn new(value: T) -> Self

impl<T> TinyPtr<T>

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

pub fn as_mut_ptr(&mut self) -> *mut T

pub unsafe fn get<'a, 'b>(&'b self) -> &'a T

pub unsafe fn get_mut<'a, 'b>(&'b mut self) -> &'a mut T

pub fn take(self) -> T

Takes ownership of the value and returns it.

The underlying memory is freed.

pub fn id(&self) -> NonZeroU16

Returns the internal id of the pointer.

This is used for debugging purposes.

Trait Implementations

impl<T> Clone for TinyPtr<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> Debug for TinyPtr<T>

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

Formats the value using the given formatter.

impl<T> From<Box<T>> for TinyPtr<T>

fn from(value: Box<T>) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for TinyPtr<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: PartialEq> PartialEq for TinyPtr<T>

fn eq(&self, other: &TinyPtr<T>) -> 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.
