内核镜像在虚拟地址空间中的偏移

fn virt_to_phys(virt: VirtAddr) -> PhysAddr

Convert virtual address to physical address

fn page_size() -> usize

fn memory_map() -> &'static [MemoryDescriptor]

fn page_table_new() -> Result<Box<dyn PageTable>, PagingError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
