Trait Implementations
impl GlobalAlloc for Allocator
[src]
unsafe fn alloc(&self, layout: Layout) -> *mut u8
[src]
unsafe fn dealloc(&self, ptr: *mut u8, layout: Layout)
[src]
unsafe fn alloc_zeroed(&self, layout: Layout) -> *mut u8
1.28.0[src]
Behaves like alloc
, but also ensures that the contents are set to zero before being returned. Read more
unsafe fn realloc(
&self,
ptr: *mut u8,
layout: Layout,
new_size: usize
) -> *mut u8
1.28.0[src]
&self,
ptr: *mut u8,
layout: Layout,
new_size: usize
) -> *mut u8
Shrink or grow a block of memory to the given new_size
. The block is described by the given ptr
pointer and layout
. Read more
impl<'a> Alloc for &'a Allocator
[src]
unsafe fn alloc(&mut self, layout: Layout) -> Result<NonNull<u8>, AllocErr>
[src]
unsafe fn dealloc(&mut self, ptr: NonNull<u8>, layout: Layout)
[src]
fn usable_size(&self, layout: &Layout) -> (usize, usize)
[src]
allocator_api
)Returns bounds on the guaranteed usable size of a successful allocation created with the specified layout
. Read more
unsafe fn realloc(
&mut self,
ptr: NonNull<u8>,
layout: Layout,
new_size: usize
) -> Result<NonNull<u8>, AllocErr>
[src]
&mut self,
ptr: NonNull<u8>,
layout: Layout,
new_size: usize
) -> Result<NonNull<u8>, AllocErr>
allocator_api
)Returns a pointer suitable for holding data described by a new layout with layout
’s alignment and a size given by new_size
. To accomplish this, this may extend or shrink the allocation referenced by ptr
to fit the new layout. Read more

&mut self,
layout: Layout
) -> Result<NonNull<u8>, AllocErr>
[src]
&mut self,
layout: Layout

, but also ensures that the contents are set to zero before being returned. Read more
unsafe fn alloc_excess(&mut self, layout: Layout) -> Result<Excess, AllocErr>
[src]
allocator_api
)Behaves like alloc
, but also returns the whole size of the returned block. For some layout
inputs, like arrays, this may include extra storage usable for additional data. Read more
