Expand description

Hardware abstraction layer for memory management.

Required Methods§

Source

fn alloc_frame() -> Option<HostPhysAddr>

Allocates a frame and returns its host physical address. The

§Returns
  • Option<HostPhysAddr> - Some containing the physical address of the allocated frame, or None if allocation fails.
Source

fn dealloc_frame(paddr: HostPhysAddr)

Deallocates a frame given its physical address.

§Parameters
  • paddr - The physical address of the frame to deallocate.
Source

fn phys_to_virt(paddr: HostPhysAddr) -> HostVirtAddr

Converts a host physical address to a host virtual address.

§Parameters
  • paddr - The physical address to convert.
§Returns
  • HostVirtAddr - The corresponding virtual address.
Source

fn virt_to_phys(vaddr: HostVirtAddr) -> HostPhysAddr

Converts a host virtual address to a host physical address.

§Parameters
  • vaddr - The virtual address to convert.
§Returns
  • HostPhysAddr - The corresponding physical address.

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.
