# Rscsv

Fast CSV using Rust extensions. Can read arrays of arrays from strings and write

strings from arrays of arrays.

[![Build Status](https://travis-ci.org/lautis/rscsv.svg?branch=master)](https://travis-ci.org/lautis/rscsv)

## Installation

This gem requires Rust (~> 1.17) and Cargo to be installed. With those

requirements fulfilled, rscsv can be installed like any other gem:

```

gem install rscsv

```

## Usage

```ruby

require 'rscsv'

Rscsv::Writer.generate_lines([['1', '2', '3'], ['3', '4', '5']])

# => 1,2,3\n4,5,6\n

Rscsv::Writer.generate_line(['1', '2', '3'])

# => 1,2,3\n

Rscsv::Reader.parse("1,2,3\n4,5,6\n")

# => [["1", "2", "3"], ["4", "5", "6"]]

# Streaming from Enumerator

Rscsv::Reader.each(["1,2,3\n","4,5,6\n"].each) do |row|

  # yields ["1", "2", "3"] and ["4", "5", "6"]

end

```

This is ~3x faster than using native Ruby `CSV.generate` or `CSV.parse`.
