UTF-8 decode

Documentation

Crate informations

Github

This crates provides incremental UTF-8 decoders implementing the Iterator trait. Thoses iterators are wrappers around u8 bytes iterators.

Decoder

The Decoder struct wraps Iterator<Item = u8> iterators. You can use it, for instance, to decode u8 slices.

extern crate utf8_decode;

use utf8_decode::Decoder;

fn main() -> std::io::Result<()> {
    let bytes = [72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33, 32, 240, 159, 140, 141];

    let decoder = Decoder::new(bytes.iter().cloned());

    let mut string = String::new();
    for c in decoder {
        string.push(c?);
    }

    println!("{}", string);

    Ok(())
}

UnsafeDecoder

The UnsafeDecoder wraps Iterator<Item = std::io::Result<u8>> iterators. You can use it, for instance, to decode UTF-8 encoded files.

extern crate utf8_decode;

use std::fs::File;
use std::io::Read;
use utf8_decode::UnsafeDecoder;

fn main() -> std::io::Result<()> {
    let file = File::open("examples/file.txt")?;

    let decoder = UnsafeDecoder::new(file.bytes());

    let mut string = String::new();
    for c in decoder {
        string.push(c?);
    }

    println!("{}", string);

    Ok(())
}
