Expand description

An immutable pointer to a value in allocated memory

Implementations§

source§

impl<T> Ptr<T>

source

pub fn new(value: T) -> Ptr<T>

Moves the provided value into newly allocated memory

source§

impl<T> Ptr<T>
where T: ?Sized,

source

pub fn ptr_eq(this: &Ptr<T>, other: &Ptr<T>) -> bool

Returns true if the two Ptrs point to the same allocation

See also: std::sync::Arc::ptr_eq

source

pub fn address(this: &Ptr<T>) -> Address

Returns the address of the allocated memory

source

pub fn ref_count(this: &Ptr<T>) -> usize

Returns the number of references to the allocated memory

Only strong references are counted, weak references don’t get added to the result.

source§

impl<T> Ptr<T>
where T: Clone,

source

pub fn make_mut(this: &mut Ptr<T>) -> &mut T

Makes a mutable reference into the owned T

If the pointer has the only reference to the value, then the reference will be returned. Otherwise a clone of the value will be made to ensure uniqueness before returning the reference.

See also: std::sync::Arc::make_mut
