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.
``` extern crate onigiri; use onigiri::tools;
fn main() { let testtext = "-123 456".tostring(); let newvvchar = tools::createvvchar(&test_text);
let new_ni32 = tools::Ni32::new(&new_vvchar[0]);
let new_ni32_2 = tools::Ni32::new(&new_vvchar[1]);
let addition = new_ni32.attr + new_ni32_2.attr;
assert_eq!(addition, 333_i32);
} ```
