Installation

Adding to Your Project

Add datalogic-rs to your Cargo.toml:

[dependencies]
datalogic-rs = "4.0"
serde_json = "1.0"

Or use cargo add:

cargo add datalogic-rs serde_json

Version Selection

v4.x (recommended): Ergonomic API with serde_json::Value, simpler to use
v3.x: Arena-based allocation for maximum raw performance

Both versions are actively maintained. Choose v4 for ease of use, v3 if you need every bit of performance.

Feature Flags

datalogic-rs has minimal dependencies by default. All features are included in the base crate.

WebAssembly Support

For WebAssembly targets, use the datalogic-wasm crate:

npm install datalogic-wasm

Or build from source:

cd datalogic-wasm
wasm-pack build --target web

Minimum Rust Version

datalogic-rs requires Rust 1.70 or later.

Verifying Installation

Create a simple test:

use datalogic_rs::DataLogic;
use serde_json::json;

fn main() {
    let engine = DataLogic::new();
    let rule = json!({ "+": [1, 2] });
    let compiled = engine.compile(&rule).unwrap();
    let result = engine.evaluate_owned(&compiled, json!({})).unwrap();

    println!("1 + 2 = {}", result);
    assert_eq!(result, json!(3));
}

Run with:

cargo run

You should see: 1 + 2 = 3
