Trait PageAlloc 

pub unsafe trait PageAlloc {
    // Required methods
    fn alloc_page(&self, size: usize) -> Result<NonNull<[u8]>, AllocError>;
    unsafe fn dealloc_page(&self, page: NonNull<[u8]>);
}

Safety

moving an implementation of this trait shouldn’t invalidate currently allocated pages.

Required Methods

fn alloc_page(&self, size: usize) -> Result<NonNull<[u8]>, AllocError>

Returns a pointer aligned to at least 4KB

unsafe fn dealloc_page(&self, page: NonNull<[u8]>)

Safety

page has to be a currently allocated page from this instance of PageAlloc
