Crate dcsv

Dynamic csv manipulation library

Dcsv is a dynamic csv container library which offers reading and writing features.

Basic

Dcsv has two major structs of Reader and VirtualData. Reader reads csv data as byte stream and return virtual data. Changes to virtual data is not linked to original source. User needs to save virtual data to desired destination.

If you want static form of data, use read_only_ref method to get data as records form.

Usage

// It is required to import VCont trait
use dcsv::VCont;
use dcsv::{Reader, VirtualData, Value};
use std::io::BufReader;
use std::fs::File;

let data: VirtualData = Reader::new()
    .use_delimiter(';')      // Default is comma
    .use_line_delimiter('|') // Default is '\n, \r\n'
    .data_from_stream(
        BufReader::new(
            File::open("file_name.csv")
                .expect("Failed to read file")
        )
    )
    .expect("Failed to retrieve csv value from file");

// Refer docs.rs for various VirtualData methods
let value : &Value = data.get_cell(1,1).expect("Failed to get cell");
