Crate czv

czv

CSV operations library for data engineering/analysis tasks.

Example

Let’s say we want to print the total number of non-header rows in our data:

use czv::{RowCount, Result};

fn main() -> Result<()> {
    let data = "\
fruits,price
apple,2.50
banana,3.00
strawberry,1.50
";
    let output = RowCount::new().file_data(data).execute()?;
    println!("{output}"); // 3
    Ok(())
}

Usage

It is recommended to use the builder structs rather than functions though both are provided.

The builder structs are provided at the top-level for ease of use.

For example use the czv::RowCount struct rather than the czv::count::row_count function.
