onigiri

onigiri is the tool of handling chars in Rust. The japanese name of rice ball is "Onigiri". In my image, a grain of rice is char. And what collected them is chars. And the seasoning of it is each structure of onigiri::tools.

I add new validator is_calc_operator and add derive PartialEq to struct Vvc

Sep 13 2018

I remove some structs. Instead of them, I added new function cast.

Sep 3 2018

I add new struct Vvc. However, I didn't changed the previous functions. Although it may be a few, someone may already be using it. I'm doing my best to develop that it can be used more easily and clearly.

Usage

You add onigiri in Cargo.toml.

[dependencies] onigiri = "0.1.7" example is as follows.

``` extern crate onigiri; use onigiri::tools;

fn main() { let testtext = "(13 + 2)".tostring();

let new_vvchar = onigiri::tools::create_vvchar(&test_text);
assert_eq!(&new_vvchar, &vec![vec!['(', '1','3'],vec!['+'],vec!['2', ')']]);

let thirteen = &new_vvchar[0][1..].to_vec();
assert_eq!(onigiri::validator::is_positive_number(&thirteen), true);

let num = onigiri::tools::cast::<u8>(&thirteen);
assert_eq!(&num, &Some(13_u8));
assert_eq!(&num.unwrap() + 2, 15_u8);

} ```
