Easily read and write homogeneous CSV data to and from 2D ndarrays.
```rust extern crate csv; extern crate ndarray; extern crate ndarray_csv;
use csv::{ReaderBuilder, WriterBuilder}; use ndarray::Array; use ndarray_csv::{read, write}; use std::fs::File; use std::io::{Read, Write};
fn main() { // Our 2x3 test array let array = Array::fromvec(vec![1, 2, 3, 4, 5, 6]).intoshape((2, 3)).unwrap();
// Write the array into the file.
{
let mut file = File::create("test.csv").expect("creating file failed");
let mut writer = WriterBuilder::new().has_headers(false).from_writer(file);
write(&array, &mut writer).expect("write failed");
}
// Read an array back from the file
let mut file = File::open("test.csv").expect("opening file failed");
let mut reader = ReaderBuilder::new().has_headers(false).from_reader(file);
let array_read = read((2, 3), &mut reader).expect("read failed");
// Ensure that we got the original array back
assert_eq!(array_read, array);
} ```
This project uses cargo-make for builds; to build,
run cargo make all.
To prevent denial-of-service attacks, do not read in untrusted CSV streams of unbounded length;
this can be implemented with std::io::Read::take.
