Rust Library for Compressing Structs.

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 = 0.2.5 comprez = 0.2.5

Example

``` use comprez_macro::Comprezable; use comprez::{*, error::{CompressError, DecompressError}};

[derive(Comprezable, Debug)]

struct MyStruct { [#maxNum=10000] //Compulsory for each field num1: u32, [#maxNum=888] num2: u16, [#maxNum=100] num3: u8, other_struct: OtherStruct, vec1: Vec }

[derive(Comprezable, Debug)]

struct OtherStruct { #[maxNum=1000000] num4: u128, }

fn main() { let demodata = Mystruct { num1: 900, num2: 100, num3: 10, otherstruct: OtherStruct { num4: 200 }, vec1: vec![1, 2, 3, 4, 5, 6, 7, 8, 9, 10], };

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);

} ```
