Usage

Put this in your Cargo.toml:

chardet = "0.2"

Then put this in your crate root:

extern crate chardet;

Using with encoding:

extern crate chardet;
extern crate encoding;
use chardet;
use std::fs::OpenOptions;
use std::io::prelude::*;
use encoding::DecoderTrap;
use encoding::label::encoding_from_whatwg_label;

// open text file
let mut fh = OpenOptions::new().read(true).open(filepath).expect(
    "Could not open file",
);
let mut reader: Vec<u8> = Vec::new();

// read file
fh.read_to_end(&mut reader).expect("Could not read file");

// detect charset of the file
let result = detect(&reader);
// result.0 Encode
// result.1 Confidence
// result.2 Language

// decode file into utf-8
let coder = encoding_from_whatwg_label(charset2encoding(&result.0));
if coder.is_some() {
    let utf8reader = coder.unwrap().decode(&reader, DecoderTrap::Ignore).expect("Error");
}
