Crate use_csv 

use-csv

Practical CSV utility primitives for lightweight delimiter detection, field escaping, and row splitting.

Warning: versions below 0.3.0 are experimental and may change as the crate matures.

Example Usage

use use_csv::{csv_join_row, detect_delimiter, parse_csv_basic, split_csv_line_basic};

let rows = parse_csv_basic("name,enabled\nRustUse,true\n");

assert_eq!(detect_delimiter("name;enabled\nRustUse;true\n"), Some(';'));
assert_eq!(split_csv_line_basic("a,\"b,c\",d"), vec!["a", "b,c", "d"]);
assert_eq!(rows[1].fields[0], "RustUse");
assert_eq!(csv_join_row(&["one", "two,three"]), "one,\"two,three\"");

Scope

• common delimiter detection for comma, tab, semicolon, and pipe separated data
• conservative quoted-field splitting
• lightweight row parsing for fixtures, CLIs, docs, and config helpers

Non-Goals

• full RFC 4180 support
• streaming CSV parsing
• encoding detection

Structs

CsvDialect

Basic dialect metadata for simple CSV handling.

CsvRow

A parsed CSV row.

Functions

count_csv_columns

Counts columns in a CSV-like line using the basic splitter.

csv_escape_field

Escapes a field for comma-separated output.

csv_join_row

Joins fields into a comma-separated row.

detect_delimiter

Detects the most likely delimiter from common candidates.

looks_like_csv

Returns true when the input looks like delimiter-separated data.

parse_csv_basic

Parses CSV-like input into rows without streaming or encoding support.

split_csv_line_basic

Splits a single CSV line using a detected delimiter or a comma fallback.
