Expand description
Functionality required for the bytes of an Allocation
.
Required Methods§
sourcefn from_bytes<'a>(slice: impl Into<Cow<'a, [u8]>>, _align: Align) -> Self
fn from_bytes<'a>(slice: impl Into<Cow<'a, [u8]>>, _align: Align) -> Self
Create an AllocBytes
from a slice of u8
.
sourcefn zeroed(size: Size, _align: Align) -> Option<Self>
fn zeroed(size: Size, _align: Align) -> Option<Self>
Create a zeroed AllocBytes
of the specified size and alignment.
Returns None
if we ran out of memory on the host.
sourcefn as_mut_ptr(&mut self) -> *mut u8
fn as_mut_ptr(&mut self) -> *mut u8
Gives direct access to the raw underlying storage.
Crucially this pointer is compatible with:
- other pointers returned by this method, and
- references returned from
deref()
, as long as there was no write.
Object Safety§
This trait is not object safe.
Implementations on Foreign Types§
source§impl AllocBytes for Box<[u8]>
impl AllocBytes for Box<[u8]>
Default bytes
for Allocation
is a Box<u8>
.
