Struct alloc::boxed::PinBox

pub struct PinBox<T: ?Sized> { /* fields omitted */ }

🔬 This is a nightly-only experimental API. (pin #49150)

A pinned, heap allocated reference.

Methods

impl<T> PinBox<T>

pub fn new(data: T) -> PinBox<T>

🔬 This is a nightly-only experimental API. (pin #49150)

Allocate memory on the heap, move the data into it and pin it.

impl<T: ?Sized> PinBox<T>

pub fn as_pin<'a>(&'a mut self) -> Pin<'a, T>

🔬 This is a nightly-only experimental API. (pin #49150)

Get a pinned reference to the data in this PinBox.

pub unsafe fn get_mut<'a>(this: &'a mut PinBox<T>) -> &'a mut T

🔬 This is a nightly-only experimental API. (pin #49150)

Get a mutable reference to the data inside this PinBox.

This function is unsafe. Users must guarantee that the data is never moved out of this reference.

Important traits for Box<I>

impl<I: Iterator + ?Sized> Iterator for Box<I> type Item = I::Item;

pub unsafe fn unpin(this: PinBox<T>) -> Box<T>

🔬 This is a nightly-only experimental API. (pin #49150)

Convert this PinBox into an unpinned Box.

This function is unsafe. Users must guarantee that the data is never moved out of the box.
