Struct Sniffer 

pub struct Sniffer { /* private fields */ }

CSV dialect sniffer using the Table Uniformity Method.

Example

use csv_nose::{Sniffer, SampleSize};

let mut sniffer = Sniffer::new();
sniffer.sample_size(SampleSize::Records(100));

let metadata = sniffer.sniff_path("data.csv").unwrap();
println!("Delimiter: {}", metadata.dialect.delimiter as char);
println!("Has header: {}", metadata.dialect.header.has_header_row);

Implementations

impl Sniffer

pub fn new() -> Self
