Intro

Add a custom derive to a struct to make it parsable from CSVs. The derive makes it possible to construct a CSVIterator over your type. The backend will ignore extra columns as necessary, and only requires that the columns which have fields in your struct exist. The String::parse<> functions are used to parse CSV fields to the datatype of the field in your struct.

Installation

toml [dependencies] easy-csv = "0.2.0" easy-csv-derive = "0.2.0" csv = "0.14.0"

csv is a sibling dependency because you have to create the csv::Reader yourself.

Usage example

```rust extern crate easy_csv;

[macro_use]

extern crate easycsvderive; extern crate csv;

use easy_csv::{CSVIterator,CSVParsable};

[derive(Debug,CSVParsable)]

struct Record { a : i32, b : i8, d : String, }

fn main() { let data = " a,b,c,d 2,-3,foo,bar";

let mut rdr = csv::Reader::from_string(data);
let iter = CSVIterator::<Record,_>::new(&mut rdr);
let res : Vec<Record> = iter.collect();
println!("{:?}", res);

} ```

Output: [Record { a: 2, b: -3, d: "bar" }]
