⚡ Quick Start

Rust

[dependencies]
veloxx = "0.3.1"

use veloxx::dataframe::DataFrame;
use veloxx::series::Series;

let df = DataFrame::new_from_csv("data.csv")?;
let filtered = df.filter(&your_condition)?;
let grouped = df.group_by(vec!["category"]).agg(vec![("amount", "sum")])?;

Python

import veloxx

df = veloxx.PyDataFrame({"name": veloxx.PySeries("name", ["Alice", "Bob"])})
filtered = df.filter([...])

JavaScript/Wasm

const veloxx = require("veloxx");
const df = new veloxx.WasmDataFrame({name: ["Alice", "Bob"]});
const filtered = df.filter(...);
