Usage

Example

use std::{error::Error, io, process};fnexample() ->Result<(),Box<dynError>>{// Build the CSV reader and iterate over each record.letmut rdr = csv::Reader::from_reader(io::stdin());for resultin rdr.records(){// The iterator yields Result<StringRecord, Error>, so we check the// error here.let record = result?;println!("{:?}", record);}Ok(())}fnmain(){ifletErr(err) =example(){println!("error running example: {}", err);        process::exit(1);}}

$ git clone git://github.com/BurntSushi/rust-csv$ cd rust-csv$ cargo run --example cookbook-read-basic < examples/data/smallpop.csv

Example with Serde

use std::{error::Error, io, process};#[derive(Debug, serde::Deserialize)]structRecord{city:String,region:String,country:String,population:Option<u64>,}fnexample() ->Result<(),Box<dynError>>{letmut rdr = csv::Reader::from_reader(io::stdin());for resultin rdr.deserialize(){// Notice that we need to provide a type hint for automatic// deserialization.let record:Record = result?;println!("{:?}", record);}Ok(())}fnmain(){ifletErr(err) =example(){println!("error running example: {}", err);        process::exit(1);}}
