Crate os_units

Source
Expand description

This crate provides a data structure for byte size. With the x86_64 crate, you can easily convert the size of physical memory pages into bytes, and bytes into the number of physical memory pages.

§Examples

use os_units::Bytes;
use x86_64::structures::paging::{PageSize, Size4KiB};

let bytes_of_kernel = Bytes::new(314159);
let pages_of_kernel = bytes_of_kernel.as_num_of_pages::<Size4KiB>();
assert_eq!(pages_of_kernel.as_usize(), 77);

let bytes_of_pages = pages_of_kernel.as_bytes();
assert_eq!(bytes_of_pages.as_usize(), 315392);

Structs§

  • Bytes
    A struct representing byte size.
  • NumOfPages
    A struct representing the number of pages.
