Struct nom::lib::std::boxed::PinBox

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

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

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)

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

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

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

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

Get a pinned reference to the data in this PinBox.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

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

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

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<R>

impl<R> Read for Box<R> where
    R: Read + ?Sized, impl<W> Write for Box<W> where
    W: Write + ?Sized, impl<I> Iterator for Box<I> where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

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

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

Convert this PinBox into an unpinned Box.

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