tiny-json-rs

A minimalistic Rust library for encoding and decoding JSON, offering a lower memory footprint alternative to serde.

Introduction

tiny-json-rs is an open-source library designed for efficiently handling JSON in Rust applications. It aims to provide functionality similar to the serde library but focuses on reducing memory usage, making it an ideal choice for resource-constrained environments or applications where performance is critical.

Features

• Efficient JSON Encoding/Decoding: Optimized for lower memory usage.
• Easy Integration: Simple API, compatible with standard Rust structs.
• Customizable: Extendable to support various data types.

Usage

Add tiny-json-rs to your Cargo.toml:

[dependencies]
tiny-json-rs = "0.2.5"

Basic Examples

Struct Definition

Define your structs and derive Deserialize and Serialize:

use tiny_json_rs::{Deserialize,Serialize};#[derive(Debug,PartialEq,Deserialize,Serialize)]pubstructA{puba:i32,pubb:String,}#[derive(Debug,PartialEq,Deserialize,Serialize)]pubstructB{puba:i32,pubb:Vec<String>,}

Can also derive custom names

#[derive(Debug,PartialEq,Deserialize,Serialize)]pubstructC{#[Rename = "CustomName"]puba:i32,pubb:String,}

Deserializing JSON

Convert a JSON string to a Rust struct:

let json = r#"{"a": 1, "b": "Hello"}"#;let parsed:A = tiny_json_rs::decode(json.to_string()).unwrap();assert_eq!(parsed.a,1);assert_eq!(parsed.b,"Hello");

Serializing to JSON

Convert a Rust struct to a JSON string:

let obj = C{a:1,b:"Hello".to_string(),};let json = tiny_json_rs::encode(obj);assert_eq!(json,r#"{"CustomName":1,"b":"Hello"}"#);

Testing

tiny-json-rs comes with a suite of tests to ensure functionality:

#[test]fntest_deserialize(){// ...}#[test]fntest_deserialize_vec(){// ...}#[test]fntest_encode_json(){// ...}
