Module std::encoding::csv

CSV parsing — pure Hew implementation.

Parse CSV data from strings or files into a table that can be queried by row/column index or column name.

Examples

import std::encoding::csv;

fn main() {
    let table = csv.parse("name,age\nAlice,30\nBob,25");
    let rows = table.rows();
    let name = table.get_by_name(0, "name");
    println(name);  // "Alice"
}

fn cols(self: Self) -> i64

Return the number of columns.

fn header(self: Self, col: i64) -> string

Return the header name for the given column index.

fn get(self: Self, row: i64, col: i64) -> string

fn get_by_name(self: Self, row: i64, col_name: string) -> string
