Crate memory_addr

memory_addr

Wrappers and helper functions for physical and virtual memory addresses.

Examples

use memory_addr::{PhysAddr, VirtAddr};

let phys_addr = PhysAddr::from(0x12345678);
let virt_addr = VirtAddr::from(0x87654321);

assert_eq!(phys_addr.align_down(0x1000usize), PhysAddr::from(0x12345000));
assert_eq!(phys_addr.align_offset_4k(), 0x678);
assert_eq!(virt_addr.align_up_4k(), VirtAddr::from(0x87655000));
assert!(!virt_addr.is_aligned_4k());
assert!(VirtAddr::from(0xabcedf0).is_aligned(16usize));

Structs

• PhysAddr
  A physical memory address.
• VirtAddr
  A virtual memory address.

Constants

• PAGE_SIZE_4K
  The size of a 4K page (4096 bytes).

Functions

• align_down
  Align address downwards.
• align_down_4k
  Align address downwards to 4096 (bytes).
• align_offset
  Returns the offset of the address within the alignment.
• align_offset_4k
  Returns the offset of the address within a 4K-sized page.
• align_up
  Align address upwards.
• align_up_4k
  Align address upwards to 4096 (bytes).
• is_aligned
  Checks whether the address has the demanded alignment.
• is_aligned_4k
  Checks whether the address is 4K-aligned.
