Struct BorrowedRawAllocation 

pub struct BorrowedRawAllocation<'a> {
    pub(crate) base_ptr: NonNull<u8>,
    pub(crate) size: usize,
    pub(crate) phantom: PhantomData<&'a ()>,
}

Represents the unique borrow of a contiguous piece of a single allocation with some layout that is used as a data copying destination. May be wholly or partially uninitialized.

This type can only be obtained through the borrow_as_slab method on RawAllocation.

Fields

base_ptr: NonNull<u8>

size: usize

phantom: PhantomData<&'a ()>

Trait Implementations

impl<'a> Slab for BorrowedRawAllocation<'a>

fn base_ptr(&self) -> *const u8

Get a pointer to the beginning of the allocation represented by self.

fn base_ptr_mut(&mut self) -> *mut u8

Get a pointer to the beginning of the allocation represented by self.

fn size(&self) -> usize

Get the size of the allocation represented by self.

fn as_maybe_uninit_bytes(&self) -> &[MaybeUninit<u8>]

Interpret a portion of self as a slice of MaybeUninit<u8>. This is likely not incredibly useful, you probably want to use Slab::as_maybe_uninit_bytes_mut

fn as_maybe_uninit_bytes_mut(&mut self) -> &mut [MaybeUninit<u8>]

Interpret a portion of self as a mutable slice of MaybeUninit<u8>.

unsafe fn assume_initialized_as_bytes(&self) -> &[u8]

Interpret self as a byte slice. This assumes that all bytes in self are initialized.

unsafe fn assume_initialized_as_bytes_mut(&mut self) -> &mut [u8]

Interpret self as a mutable byte slice. This assumes that all bytes in self are initialized.

unsafe fn assume_range_initialized_as_bytes<R>(&self, range: R) -> &[u8]

where R: SliceIndex<[MaybeUninit<u8>], Output = [MaybeUninit<u8>]>,

Interpret a range of self as a byte slice. This assumes that all bytes within range are initialized.

unsafe fn assume_range_initialized_as_bytes_mut<R>( &mut self, range: R, ) -> &mut [u8]

where R: SliceIndex<[MaybeUninit<u8>], Output = [MaybeUninit<u8>]>,

Interpret a range of self as a mutable byte slice. This assumes that all bytes within range are initialized.
