rustHow to read CSV file in Rust

Reading a CSV file in Rust is relatively straightforward. The easiest way to do this is to use the csv crate, which provides a Reader type that can be used to iterate over the records in a CSV file. To use the crate, you first need to add it to your Cargo.toml file. Then, you can create a Reader instance and use its methods to read the CSV file. For example, the following code snippet reads a CSV file and prints out each record:

use csv::Reader;

fn main() {
    let mut rdr = Reader::from_path("my_file.csv").unwrap();
    for result in rdr.records() {
        let record = result.unwrap();
        println!("{:?}", record);
    }
}

The output of this code would be something like:

[1, "John", "Doe"]
[2, "Jane", "Smith"]

The Reader type provides several methods for reading CSV files, such as records() which returns an iterator over the records in the file, and deserialize() which can be used to deserialize each record into a Rust struct. For more information, please refer to the csv crate documentation.
