comprez_macro's Introduction

Rust Library for Compressing Structs and Enums.

A rust library for compressing and decompressing structs. Note that the library is still under heavy development and breaking changes may occur.

Description

The library is not complete yet, For now only struct with unsigned integers fields are supported. Many more will come. Stay tune.

Installation

Put this into your cargo.toml

[dependencies]
comprez_macro = 0.2.7
comprez = 0.2.7

Example

use comprez_macro::Comprezable;
use comprez::comprezable::Comprezable;   

#[derive(Comprezable, Debug, Clone)]
struct MyStruct {
    [#maxNum=10000] //Compulsory for each integer field except for u8
    num1: u32,
    [#maxNum=888]
    num2: u16,
    [#maxNum=100]
    num3: i8, //use i8 instead of u8
    other_struct: OtherStruct,
    vec1: Vec<u8>,
    vec2: Vec<OtherStruct>,
    enum1: MyEnum::Num5(10)
}

#[derive(Comprezable, Debug, Clone)]
struct OtherStruct {
    #[maxNum=1000000]
    num4: u128,
}

#[derive(Comprezable, Debug, Clone)]
enum MyEnum {
    #[maxNum=100]
    Num5(u32),
    Vec3(Vec<u8>)
}

fn main() {
    let demo_data = Mystruct {
        num1: 900,
        num2: 100,
        num3: 10,
        other_struct: OtherStruct { num4: 200 },
        vec1: vec![1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
        vec2: vec![OtherStruct{num4: 100}, OtherStruct{num4: 200}],
    };
    
    let compressed = demo_data.compress().unwrap();
    let compressed_bytes = compressed.to_bytes();
    let compressed_binaries = compressed.to_binaries();

    let compressed = Compressed::from_bytes(compressed_bytes);
    let compressed = Compressed::from_binaries(compressed_binaries);
    let decompressed = Mystruct::decompressed(compressed).unwrap();
    println!("{:?}", decompressed);
}
