Trait Implementations

source

impl GlobalAlloc for KernelAlloc

source

unsafe fn alloc(&self, layout: Layout) -> *mut u8

Allocate memory as described by the given layout. Read more

source

unsafe fn dealloc(&self, ptr: *mut u8, _layout: Layout)

1.28.0 · source

unsafe fn alloc_zeroed(&self, layout: Layout) -> *mut u8

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
