ByteSize is a semantic wrapper for byte count representations.

Features:

• Pre-defined constants for various size units (e.g., B, Kb, Kib, Mb, Mib, Gb, Gib, ... PB).
• ByteSize type which presents size units convertible to different size units.
• Arithmetic operations for ByteSize.
• FromStr impl for ByteSize, allowing for parsing string size representations like "1.5KiB" and "521TiB".
• Serde support for binary and human-readable deserializers like JSON.

Examples

Construction using SI or IEC helpers.

use bytesize::ByteSize;

assert!(ByteSize::kib(4) > ByteSize::kb(4));

Display as human-readable string.

use bytesize::ByteSize;

assert_eq!("518.0 GiB", ByteSize::gib(518).display().iec().to_string());
assert_eq!("556.2 GB", ByteSize::gib(518).display().si().to_string());
assert_eq!("518.0G", ByteSize::gib(518).display().iec_short().to_string());

Arithmetic operations are supported.

use bytesize::ByteSize;

let plus = ByteSize::mb(1) + ByteSize::kb(100);
println!("{plus}");

let minus = ByteSize::tb(1) - ByteSize::gb(4);
assert_eq!(ByteSize::gb(996), minus);
