pub struct UninitBox { /* fields omitted */ }

An uninitialized piece of memory

Implementations

impl UninitBox[src]

pub fn layout(&self) -> Layout[src]

The layout of the allocation

pub fn new<T>() -> Self[src]

create a new allocation that can fit the given type

pub fn from_layout(layout: Layout) -> Self[src]

Create a new allocation that can fit the given layout

pub fn init<T>(self, value: T) -> Box<T>[src]

Initialize the box with the given value,

Panic

if std::alloc::Layout::new::<T>() != self.layout() then this function will panic

pub fn init_with<T, F: FnOnce() -> T>(self, value: F) -> Box<T>[src]

Initialize the box with the given value,

Panic

if std::alloc::Layout::new::<T>() != self.layout() then this function will panic

pub fn as_ptr(&self) -> *const ()[src]

Get the pointer from the UninitBox

This pointer is not valid to write to

pub fn as_mut_ptr(&mut self) -> *mut ()[src]

Get the pointer from the UninitBox
