HumanByte-Derive

HumanByte Derive is a procedural macro crate for deriving HumanByte functions for deriving byte-like new types.

Usage

Add this to your Cargo.toml:

With serde support

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

Without serde support

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

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

use humanbyte_derive::HumanByte;

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

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

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

See the documentation for ByteSize to see more examples of what you can do with the HumanByte new type (just replace ByteSize 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:

• HumanByteConstructor
• HumanByteDisplay
• HumanByteParse
• HumanByteOps
• HumanByteFromStr
• HumanByteSerde (requires the serde feature)
