Trait Implementations§
source§impl GlobalAlloc for BumpAllocator
impl GlobalAlloc for BumpAllocator
Integer arithmetic in this global allocator implementation is safe when
operating on the prescribed HEAP_START_ADDRESS
and HEAP_LENGTH
. Any
other use may overflow and is thus unsupported and at one’s own risk.
source§unsafe fn alloc(&self, layout: Layout) -> *mut u8
unsafe fn alloc(&self, layout: Layout) -> *mut u8
