Crate os_units

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

Currently, this crate only supports Rust nightly version because of using const_fn feature.

Examples

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

let bytes_of_kernel = Size::<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 bytes.
NumOfPages	A struct representing the number of physical pages.
Size	A struct containing the value with the unit specified by generic type.

Traits

Unit	A marker trait for representing units.
