HumanByte

HumanByte is a procedural macro crate for deriving HumanByte functions for new types of the form Foo(u64).

It provides human-friendly way of constructing and displaying the type with byte units.

Usage

Add this to your Cargo.toml:

[dependencies]
humanbyte = { version = "0.1", features = ["serde"] }

[dependencies]
humanbyte = { version = "0.1" }

[dependencies]
humanbyte = { version = "0.1", no-default-features = true }

Next, define your new type and derive HumanByte for it:

use humanbyte_derive::HumanByte;

#[derive(HumanByte)]
pub struct Foo(u64);

This will derive all the necessary functions for your new type. You can then use it like this:

let size = Foo::mb(1);
assert_eq!(size.to_string(), "1.0 MB");

See the documentation for bytescale to see more examples of what you can do with the HumanByte new type (just replace Foo with your own type name).

In addition, if you only want some of the HumanByte functions derived, you can use any of the following derives in an a la carte fashion:
