Native Rust implementation of Apache Arrow

Build Status Coverage Status


This is a starting point for a native Rust implementation of Arrow.

The current code demonstrates arrays of primitive types and structs.

Creating an Array from a Vec

// create a memory-aligned Arrow array from an existing Vec
let array = PrimitiveArray::from(vec![1, 2, 3, 4, 5]);

println!("array contents: {:?}", array.iter().collect::<Vec<i32>>());

Creating an Array from a Builder

let mut builder: Builder<i32> = Builder::new();
for i in 0..10 {
let buffer = builder.finish();
let array = PrimitiveArray::from(buffer);

println!("array contents: {:?}", array.iter().collect::<Vec<i32>>());

Run Examples

Examples can be run using the cargo run --example command. For example:

cargo run --example array_from_builder

Run Tests

cargo test
