pub fn [new](#method.new)(x: T) -> [Box](../../std/boxed/struct.Box.html "struct std::boxed::Box")<T>[src]
Allocates memory on the heap and then places x into it.
This doesn't actually allocate if T is zero-sized.

pub unsafe fn [from_raw](#method.from%5Fraw)(raw: [*mut T](../primitive.pointer.html)) -> [Box](../../std/boxed/struct.Box.html "struct std::boxed::Box")<T>
1.4.0
Constructs a box from a raw pointer.
After calling this function, the raw pointer is owned by the resulting Box. Specifically, the Box destructor will call the destructor of T and free the allocated memory. Since the way Box allocates and releases memory is unspecified, the only valid pointer to pass to this function is the one taken from another Box via the Box::into_raw function.
This function is unsafe because improper use may lead to memory problems. For example, a double-free may occur if the function is called twice on the same raw pointer.
let x = Box::new(5); let ptr = Box::into_raw(x); let x = unsafe { Box::from_raw(ptr) };Run
pub fn [into_raw](#method.into%5Fraw)(b: [Box](../../std/boxed/struct.Box.html "struct std::boxed::Box")<T>) -> [*mut T](../primitive.pointer.html)
1.4.0
Consumes the Box, returning the wrapped raw pointer.
After calling this function, the caller is responsible for the memory previously managed by the Box. In particular, the caller should properly destroy T and release the memory. The proper way to do so is to convert the raw pointer back into aBox with the Box::from_raw function.
Note: this is an associated function, which means that you have to call it as Box::into_raw(b) instead of b.into_raw(). This is so that there is no conflict with a method on the inner type.
let x = Box::new(5); let ptr = Box::into_raw(x);Run
pub fn [into_raw_non_null](#method.into%5Fraw%5Fnon%5Fnull)(b: [Box](../../std/boxed/struct.Box.html "struct std::boxed::Box")<T>) -> [NonNull](../../std/ptr/struct.NonNull.html "struct std::ptr::NonNull")<T>[src]
🔬 This is a nightly-only experimental API. (box_into_raw_non_null #47336)
Consumes the Box, returning the wrapped pointer as NonNull<T>.
After calling this function, the caller is responsible for the memory previously managed by the Box. In particular, the caller should properly destroy T and release the memory. The proper way to do so is to convert the NonNull<T> pointer into a raw pointer and back into a Box with the Box::from_rawfunction.
Note: this is an associated function, which means that you have to call it as Box::into_raw_non_null(b)instead of b.into_raw_non_null(). This is so that there is no conflict with a method on the inner type.

`pub fn leak<'a>(b: Box) -> &'a mut T where
T: 'a, `[src]
🔬 This is a nightly-only experimental API. (box_leak #46179)
needs an FCP to stabilize
Consumes and leaks the Box, returning a mutable reference,&'a mut T. Here, the lifetime 'a may be chosen to be 'static.
This function is mainly useful for data that lives for the remainder of the program's life. Dropping the returned reference will cause a memory leak. If this is not acceptable, the reference should first be wrapped with the Box::from_raw function producing a Box. This Box can then be dropped which will properly destroy T and release the allocated memory.
Note: this is an associated function, which means that you have to call it as Box::leak(b) instead of b.leak(). This is so that there is no conflict with a method on the inner type.
Simple usage:
#![feature(box_leak)]
fn main() { let x = Box::new(41); let static_ref: &'static mut usize = Box::leak(x); *static_ref += 1; assert_eq!(*static_ref, 42); }Run
Unsized data:
#![feature(box_leak)]
fn main() { let x = vec![1, 2, 3].into_boxed_slice(); let static_ref = Box::leak(x); static_ref[0] = 4; assert_eq!(*static_ref, [4, 2, 3]); }Run
