Struct ndarray_npy::NpzWriter

pub struct NpzWriter<W: Write + Seek> { /* fields omitted */ }

Writer for .npz files.

Example

use ndarray::{array, Array1, Array2};
use ndarray_npy::NpzWriter;
use std::fs::File;

let mut npz = NpzWriter::new(File::create("arrays.npz")?);
let a: Array2<i32> = array![[1, 2, 3], [4, 5, 6]];
let b: Array1<i32> = array![7, 8, 9];
npz.add_array("a", &a)?;
npz.add_array("b", &b)?;

Methods

impl<W: Write + Seek> NpzWriter<W>

pub fn new(writer: W) -> NpzWriter<W>

Create a new .npz file without compression. See numpy.savez.

pub fn new_compressed(writer: W) -> NpzWriter<W>

Creates a new .npz file with compression. See numpy.savez_compressed.

pub fn add_array<N, S, D>(
    &mut self,
    name: N,
    array: &ArrayBase<S, D>
) -> Result<(), WriteNpzError> where
    N: Into<String>,
    S::Elem: WritableElement,
    S: Data,
    D: Dimension, 

Adds an array with the specified name to the .npz file.
