Write a csv parser in Rust
user
here's a simple implementation of a csv (comma separated values) parser in rust. this parser reads a csv file and prints the contents in the console.
```rust
use std::fs::file;
use std::io::{bufread, bufreader};
use std::error::error;

fn main() -> result<(), box<dyn error>> {
    let file_path = "example.csv"; // replace with your csv file path

    let file = file::open(file_path)?;
    let reader = bufreader::new(file);

    let mut rows = vec::new();

    for line in reader.lines() {
        let line = line?;
        let values: vec<string> = line.split(",").map(|value| value.to_owned()).collect();
        rows.push(values);
    }

    for row in rows {
        for (index, value) in row.iter().enumerate() {
            println!("{:?}", value);
        }
        println();
    }

    ok(())
}
```
this implementation uses the `bufreader` to read the file line by line. each line is then split by the `,` character, and the resulting substrings are stored in a `vec` of `string`s. these `vec`s are then stored in a 2d `vec`, representing the rows of the csv file. the contents of the csv file are printed to the console.

please replace `"example.csv"` with your actual csv file path. you can also modify this simple parser to add more features like error handling or an iterator for easier access to the data.
