pub struct Allocation<'a, T = u8> {
    pub ptr: NonNull<T>,

    pub level: Level,
}
Expand description

A successful allocation and current Level.

Fields§

§ptr: NonNull<T>

Pointer to the uninitialized region with specified layout.

§lifetime: AllocTime<'a>

The lifetime of the allocation.

§level: Level

The observed amount of consumed bytes after the allocation.

Implementations§

source§

impl<'alloc, T> Allocation<'alloc, T>

source

pub unsafe fn leak(self, val: T) -> &'alloc mut T

Write a value into the allocation and leak it.

§Safety

Must have been allocated for a layout that fits the layout of T previously. The pointer must not be aliased.

§Usage

Consider the alternative Bump::leak to safely allocate and directly leak a value.

source

pub unsafe fn boxed(self, val: T) -> LeakBox<'alloc, T>

Write a value into the allocation and own it.

§Safety

Must have been allocated for a layout that fits the layout of T previously. The pointer must not be aliased.

§Usage

Consider the alternative Bump::leak to safely allocate and directly leak a value.

source

pub unsafe fn uninit(self) -> &'alloc mut MaybeUninit<T>

Convert this into a mutable reference to an uninitialized slot.

§Safety

Must have been allocated for a layout that fits the layout of T previously.
