digit-sequence

Sequence of u8 digits

This Rust crate revolves around the DigitSequence struct, a sequence of 0-9 u8 digits, with:

• conversions from integers, numeric sequences and strings

• different iteration strategies

• a custom Result and a custom Error.

• optional serde I/O

use digit_sequence::*;

fn main() -> GenericResult<()> {
    assert_eq!(DigitSequence::new(), []);
    assert_eq!(DigitSequence::default(), []);

    let sequence: DigitSequence = [3, 8, 7].try_into()?;
    assert_eq!(sequence, [3, 8, 7]);

    assert_eq!(format!("{:?}", sequence), "DigitSequence([3, 8, 7])");
    assert_eq!(sequence.to_string(), "387");

    let mapped_vec: Vec<u8> = sequence.iter().map(|digit| digit + 1).collect();
    assert_eq!(mapped_vec, vec![4, 9, 8]);

    let number: u16 = sequence.try_into()?;
    assert_eq!(number, 387);

    Ok(())
}

Features

This crate supports the following optional features:
