[deprecated] Parsing the byte sequence of the ascii characters and safely converting them to integers.

Atoi

Parsing the byte sequence of the ascii characters and safely converting them to integers.

Capabilities:

1. Convert ASCII byte sequences to integer primitives Rust.
2. Protection against overflow of numbers
3. Accounting for the features of signed, unsigned primitives
4. Return of the transfer in case of an error
5. Using IterByteArray

Use:

#1

extern crate cluatoi;
use cluatoi::Atoi;

fn main() {
    let isize = isize::atoi(b"-1245").unwrap(); 		
    //-1245isize

    let usize = usize::atoi(b"1245").unwrap();
    //1245usize

    let my_int = u64::atoi_stop(b"1245T", b'T').unwrap(); 	
    //1245u64

    let my_int = u64::atoi_iter(b"1245".iter()).unwrap(); 	
    //1245u64
}

#2

extern crate cluatoi;
use cluatoi::Atoi;

fn main() {
    let array = b"1024!18446744073709551610!-1!X";
    let mut array_iter = array.iter();


    let num_0 = u64::atoi_iter_wait_stop(&mut array_iter, b'!').unwrap(); 
    //1024u64

    let num_1 = u64::atoi_iter_wait_stop(&mut array_iter, b'!').unwrap(); 
    //18446744073709551610u64

    let num_err = usize::atoi_iter_wait_stop(&mut array_iter, b'!');
    //ERROR, ISIZE VALUE + USIZE TYPE
    //Err(ByteUnk(45))

    let end_byte = array_iter.next().unwrap();
    //X

    println!("{}!{}!{:?}!{}", num_0, num_1, num_err, end_byte);
    //1024!18446744073709551610!Err(ByteUnk(45))!88
}

Russian:

Разбор байтовой последовательности символов ascii и безопасное преобразование их в целые числа.

Возможности:

1. Преобразование ASCII byte последовательности в целочисленные примитивы Rust.
2. Защита предотвращяющяя переполнения чисел
3. Учет особенностей signed, unsigned примитивов
4. Возврат перечисления в случае ошибки
5. Использование IterByteArray

cluatoi's Issues

Specifying offset and size

atoi_end does not allow you to specify the offset size, which limits the scope
New API Example:

fn main() {

	let array_end = b"xza1245ssfsadfasdasd";

	let my_int = u64::atoi_end(array_end, 3u16, 4u16).unwrap(); //1245u64

}

Using cluAtoi to convert 16-digit numbers

I suggest adding conversion support for 16-digit numbers.
API Example:

extern crate cluatoi;
use cluatoi::Atoi;

fn main() {

	let array = b"-0xFF";
	let isize = isize::atoi16(array).unwrap(); //  255isize

	let usize = usize::atoi16(array).unwrap();  //  AtoiErr(ByteUnk(b'-'))

}
